Motivated by political regulations and rising energy prices, companies strive for implementing energy management and for reducing their energy consumption. It is an expenditure of work for the energy manager to gather all relevant information about the facilities and machines (e.g. meaning of measurement and control signals, limits of these quantities, installed nominal capacities). In many cases, there is digital planning data from the planning, construction and commissioning phases. Using automationML, this information can be used collaboratively not only for engineering and maintenance but for energy monitoring and optimization. In this study, an industrial robot and two conveyors are integrated in the wide-spread energy management software suite EnEffCo. We document the method and results. Implications for deriving optimization formulations are discussed.

作者： Gregor Thiele Niloufar Khorsandi Jörg Krüger Department for Process Automation and Robotics Institute for Production Systems and Design Technology Berlin Germany Department for Industrial Automation Technology Technical University of Berlin Berlin Germany

Industrial facilities are complex and heterogeneous systems in permanent technological change. The ambitions towards smart factories heighten the requirements for the flexible interconnection of various devices. These industrial entities are controlled, observed and optimized by many services. The tuning of process parameters of several linked components in order to boost the overall energy efficiency is one example of such services. automationML (AML) provides a hierarchical description language for industrial systems considering both structure and properties. An extension of the established standard allows for intuitive modeling of energy optimization problems. An approved energy performance indicator (EnPI) methodology was integrated in the libraries of AML in order to simplify and shorten the modeling procedure for the optimization task. The procedure is demonstrated using the example of an industrial cooling system.

A practical approach to reduce energy consumption in a serial production environment by shutting down subsystems of a machine tool

引用

Procedia Manufacturing 2019年 33卷 343-350页

Energy efficiency in production is becoming increasingly important for the automotive industry, motivated by political regulations and competitiveness. Many theoretical approaches to achieve an efficient production via advanced control have only been tested in experimental environments. Important for the transfer into serial production is the proof that all requirements (e.g. quantity and quality) will be met. For ensuring production on demand, machine tools (MT) imitate the real production process to keep themselves at operating temperature. All subsystems of a MT operate at full power in this state, disregarding its necessity. Shutting down these subsystems during non-productive periods is a promising approach for saving energy. This paper will present a method for shutting down components during non-productive periods, while ensuring the ability to produce on demand. Successful tests were already performed during live operation in a plant of a car manufacturer in Berlin, Germany.

Finite-time asynchronous dissipative filtering of conic-type nonlinear Markov jump systems

Science China(Information Sciences) 2021年第5期64卷 151-162页

作者： Xiang ZHANG Shuping HE Vladimir STOJANOVIC Xiaoli LUAN Fei LIU Key Laboratory of Intelligent Computing and Signal Processing (Ministry of Education) School of Electrical Engineering and Automation Anhui University Department of Automatic Control Robotics and Fluid Technique Faculty of Mechanical and Civil EngineeringUniversity of Kragujevac Key Laboratory of Advanced Process Control for Light Industry (Ministry of Education) Institute of AutomationJiangnan University

In the present study, the finite-time asynchronous dissipative filter design problem for the Markov jump systems with conic-type nonlinearity is studied. The hidden Markov model can describe the asynchronism embodied in the system modes and the filter modes reasonably. Moreover, a suitable LyapunovKrasovskii function is utilized and linear matrix inequalities are applied to obtain adequate conditions. These techniques guarantee the finite-time boundedness and strict dissipativity of the filtering error dynamic system. Furthermore, the design problems of the passive filter and the H∞ filter are studied by adjusting the three parameters U, G and V. Finally, the filter gains and the optimal index α*are obtained and the correctness and feasibility of the designed approach are verified by a simulation example.

This paper presents the development and implementation of an automated control system for the technological process of casting reactoplastic products in a laboratory environment. The primary objective is to design an integrated control system and a comprehensive software suite to manage process parameters, enabling the use of various grades of reactoplastics efficiently. The development process involved creating a detailed electrical schematic and an operational algorithm for the equipment. Essential components were meticulously selected to construct a laboratory prototype, leading to the establishment of a reliable automated control system. Additionally, a sophisticated software suite was developed and registered with Rospatent, ensuring intellectual property protection. Extensive experimental casting trials were conducted, resulting in high-quality plastic part samples that demonstrate the system's effectiveness. The proposed system showcases significant advancements in improving the quality and efficiency of small-batch production of plastic components, highlighting its potential for broader industrial applications.

Safety critical systems are typically subjected to hazard analysis before commissioning to identify and analyse potentially hazardous system states that may arise during operation. Currently, hazard analysis is mainly based on human reasoning, past experiences, and simple tools such as checklists and spreadsheets. Increasing system complexity makes such approaches decreasingly suitable. Furthermore, testing-based hazard analysis is often not suitable due to high costs or dangers of physical faults. A remedy for this are model-based hazard analysis methods, which either rely on formal models or on simulation models, each with their own benefits and drawbacks. This paper proposes a two-layer approach that combines the benefits of exhaustive analysis using formal methods with detailed analysis using simulation. Unsafe behaviours that lead to unsafe states are first synthesised from a formal model of the system using Supervisory Control Theory. The result is then input to the simulation where detailed analyses using domain-specific risk metrics are performed. Though the presented approach is generally applicable, this paper demonstrates the benefits of the approach on an industrial human-robot collaboration system.

IFAC Proceedings Volumes 2005年第1期38卷 181-186页

作者： Binrui Wang Xinhe Xu Jindong Tan Key Laboratory of Process Industry Automation Ministry of Education Institute of AI and Robotics Northeastern University Shenyang 110004 China Department of Electrical and Computer Engineering Michigan Technological University Houghton MI 49931 USA

Intelligent bionic leg (IBL) is important for above-knee amputees. Biped robot with heterogeneous legs (BRHL) including artificial leg and bionic leg is proposed as a good test-bed for IBL. Mechanism and virtual prototype of BRHL is designed and built. Model of BRHL is established. Based on the complex differential algebraic equation of bionic leg, computed torque and PD feedback control of joint angle are introduced for gait tracking. The iterative learning control is applied in conjunction with computed torque and PD control law for good tracking performance. Control simulation is done and shows intelligent control is good for BRHL.

ASTM E1989-98 — The New Instrument Control Standard

引用

SLAS Technology 1999年第3期4卷 40-42页

作者： Torsten A. Staab John W. Elling U.S. Department of Energy Los Alamos National Laboratory Engineering Sciences and Applications Division Energy and Process Engineering Group Automation and Robotics Team Los Alamos NM 87545 USA

The new ASTM E1989–98 Laboratory Equipment Control Interface Specification (LECIS) is a robust standard definition of equipment behavior while under remote control. The goal of the standardization effort is to facilitate “plug-and-play” integration of laboratory automation with standard hardware behavior and software interfaces. The LECIS standardizes laboratory equipment behavior and a message passing scheme between the controller and equipment that synchronizes this behavior. Commercial adoption of this new standard is well under way.
