In this paper, we propose a hybrid algorithm that combines an improved Artificial Potential Field (APF) method with the Simulated Annealing (SA) algorithm for path planning of an electric power operation robot manipulator in complex distribution grid environments. To address the unreachable target issue inherent in traditional APF, we introduce a distance regulation factor to optimize the repulsive function. This modification allows the manipulator to smoothly approach the target point as it nears, while the repulsion from obstacles gradually decreases. Additionally, to overcome the limitations of the traditional SA algorithm, such as its tendency to get trapped in local minimum solutions and its inefficiency in complex environments, we propose an adaptive temperature rise strategy. This strategy increases the temperature, enhancing the probability of escaping local optimal solutions. When the APF algorithm becomes trapped in a local optimum, the improved SA algorithm is applied to escape the local minimum. Once the local optimum is avoided, the algorithm switches back to APF to continue the path planning process. Simulation results demonstrate that the proposed improved APF-SA algorithm adapts effectively to various complex environments, achieving shorter planning times and higher success rates compared to traditional APF and SA algorithms. It successfully resolves the unreachable target and local minimum problems associated with APF. Finally, the feasibility of the proposed APF-SA fusion algorithm is validated through experiments conducted on an electric power operation robot experimental platform for distribution grid applications.

process controls (basic as well as advanced) are implemented within the process control system, which may mean a distributed control system (DCS), programmable logic controller (PLC), and/or a supervisory control computer. DCSs and PLCs are typically industrially hardened and fault-Tolerant. Supervisory control computers are often not hardened or fault-Tolerant, but they bring a higher level of computational capability to the control system, to host valuable, but not critical, advanced control applications. advanced controls may reside in either the DCS or the supervisory computer, depending on the application. Basic controls reside in the DCS and its subsystems, including PLCs. Because we usually deal with real-world systems with real-world constraints (cost, computer resources, size, weight, power, heat dissipation, etc.), it is understood that the simplest method to accomplish a task is the one that should be used. Experts usually rely on common sense when they solve problems. They also use vague and ambiguous terms. Other experts have no difficulties with understanding and interpreting this statement because they have the background to hearing problems described like this. However, a knowledge engineer would have difficulties providing a computer with the same level of understanding. In a complex industrial process, how can we represent expert knowledge that uses vague and fuzzy terms in a computer to control it? In this context, the application is developed to control the pretreatment and pasteurization station of milk localized in Batna (Algeria) by adopting a control approach based on expert knowledge and fuzzy logic. © 2018 IEEE.

The Malampaya Deepwater Gas-to-Power project, the single biggest industrial investment to date in the Philippines, supplies clean, environment-friendly fuel to service 30% of Luzon's power generation requirements. Subsea wells and a manifold gather gas and liquid and control the flow to a shallow water platform. Here, gas and condensate are separated before transporting dry gas through a 504 km long pipeline to an onshore gas plant. A key challenge of the Malampaya offshore facility is to maintain a smooth, continuous operation under varying demands of gas delivery from the onshore gas plant, which often leads to slugging at low flow rates. This paper focuses on the successful implementation of Halliburton's advanced process automation solutions to improve operation of the offshore platform. The applied solutions include advanced control applications to better control production and the operation of the methanol recovery column and an alarm management system to improve the effectiveness of the alarm system that enables the operators to better respond to abnormal operating conditions. A core principle of the advanced control application for production control is to maximize the use of topside installed capacity to better handle production rate changes while maintaining the stability of the export gas compressor and the liquid processing equipments, particularly at low production levels. As part of the implementation of the advanced control applications, some advanced regulatory control improvements to the compressor systems were required to automate speed control for the compressor and to reduce recycling. The alarm management system allows regular analysis of alarm activity and identifies "bad actors". The project included the execution of a rigorous alarm rationalization procedure, which reduced the number of unnecessary alarms considerably and allowed the operator to focus on the needed areas of action during abnormal operation.

In 2002 DC Water entered into a process control System (PCS) automation contract. The objective of this project was to implement a new PCS for the entire Blue Plains advanced Wastewater Treatment (AWTP). The $34 Million, ten-year project was scheduled to be implemented in multiple phases that were dependent on the schedules of ongoing Capital Improvement Projects (CIP) at the Blue Plains AWTP. Some of the goals and objectives included: • Gaining stakeholder acceptance and meeting their goals, including the operations and maintenance groups for the control and operation of the overall facility • Coordinating with a large and changing Capital Improvement Plan (CIP) for planned plant upgrades and modifications • Training and knowledge transfer to DC Water, to be self-sufficient and not reliant on the vendor for ongoing maintenance of the system For the phased approach to be successful, PCS aspects such as installation and configuration of the Distributed controllers Units (DCU) had to be closely coordinated with ongoing design and construction projects. The PCS program was developed with flexibility to accommodate future expansion and new processes. The Filtrate Treatment Facility, Combined Heat and Power (CHP), and Enhanced Clarification Facility are significant new processes that have recently been added to PCS network. These processes were not envisioned or included in the Facilities Plan when the PCS project started in 2002. However, the built-in system flexibility allowed these large and complex projects to be incorporated into the overall PCS with no negative impact on system-performance. During 1980s and 1990s there were various attempts to implement PCS automation systems with no success, primarily due to lack of stakeholders' involvement and buy-in. Other previous automation pitfalls at the Blue Plains AWTP included: no user or team commitments, no human factors considerations, and lack of buy-in because the implementation was vendor and technology driven vs.

Analysis of Phase-Space and Psychoacoustic Measures for Condition Monitoring of Milling Tools

IEEE Transactions on Instrumentation and Measurement 2025年 74卷

This article presents a thorough analysis and evaluation of condition monitoring (CM) of a precision computer numerical control (CNC) mill based on acoustic emissions (AEs). Two separate techniques are used to analyze the data: the first computes metrics after representing the data in the phase space, in contrast to classical approaches that operate in the time and frequency domains. The second approach uses psychoacoustic metrics. Through the analysis of data in the phase domain, which is linked to the angular position of the milling tool, high angular resolution for the acoustic tool monitoring is achieved, enabling the evaluation of each cutting edge of the milling tool individually. The obtained results are consistent with those of direct measurement methods, in this case based on microscopic photographs. On the other hand, since the AE data are audible, the use of psychoacoustic metrics in CM is also investigated, with the goal to create a link to human perception of anomalies based on hearing the AEs. In order to evaluate the AE data, two relative metrics for wear and accumulated tool damage are defined in the phase space;additionally, several psychoacoustic metrics are investigated. The methods were evaluated on large datasets acquired during the production of a series of parts and by using different tools. The relative metrics in the phase space provide robust and meaningful results and are performing better than the psychoacoustic metrics since they effectively embed a priori knowledge about the tool geometry into the evaluation. © 1963-2012 IEEE.

TOWARDS IMPROVED automation FOR DESALINATION processES .1. advanced control

The desalination process industries have largely tried to solve control problems by conventional rather than modern control techniques that are attracting widespread industrial applications and revolutionizing process control as a result of advances in control theory. control systems are designed from mathematical models that are generally imperfect descriptions of real processes. It is widely accepted that conventional PID or PI controllers may not provide satisfactory performance in view of nonlinearity and uncertainty in the real world of desalination processes. It is essential that control systems operate satisfactorily over a wide range of process conditions. The practice of multi stage flash (MSF) desalination process control, process design, optimization, conspicuously lags behind contemporary theoretical developments. Conventional process control techniques do not ensure the safest and the most profitable operation of processes when compared with advanced process control which uses the knowledge of process economics and provides insight into the process to maintain essential variables at optimum setpoints. This paper is an attempt to promote excellence and innovation in desalination engineering and to remove barriers to advanced process control. Attempted here is brief clarification of some aspects of advanced control strategies in terms of answers to the questions: Advance control strategies: What are they? Where and when are they applicable? and What can be expected of them? Although the reference here is to MSF plants, some of the observations and remarks are also relevant to process control practice in general. In the end, the conclusions point out the complexity of the real world control problem which behoves us to advocate the application of techniques such as self-optimizing control strategies and artificial intelligence (AI) leading to an integrated system of intelligent control.

APPLICATION OF PATTERN RECOGNITION METHODS TO control SYSTEMS.

引用

Proceedings of the IEEE conference on Decision and control 1979年 2卷 796-801页

作者： Saridis, George N.

Pattern recognition methods, capable of intelligent decision making without a precise description of the process model have been used in many cases to implement advanced control systems. Such techniques have been applied for structural identification of nonlinear systems, to direct control of systems operating in uncertain environments to quality process control. Finally pattern recognition methods may be used to implement the higher levels of intelligent control systems where advanced decision making is required. An account of these techniques and their application to controls are given. Possible new applications to socioeconomic, bioengineering, transportation and robotic systems, man-machine interactive systems and other advanced automation systems are discussed.

Complex interfaces for communication and accessing online process data are two typical plagues when integrating advanced applications into process industry plants. Examples of such advanced applications are process validation, online optimisation, advanced controllers, etcetera. Today's typical procedure is to either integrate the additional functionality directly into the particular automation system or to add it as an additional external system above the automation system level. The first procedure is often not feasible due to limited resources and restricted integration capabilitites of industrial automation systems. On the other hand, external solutions impose additional communication load and error proneness on automation systems. Also, the integarated required increases: communication failures, such as missing setpoints, need to be handled properly within the automation system in order to avoid loosing closed loop control and to fail back to automation system-internal strategies. These barriers hinder widespread usage of advanced applications. Thus, a different integration approach provides additional application functionality and data access directly on the field level. Fieldbus technology is an established technology providing standardised data access. In this paper, we present a flexible solution for easily realising virtual field devices hosting diverse applications (for instance, using common PC hardware).
