The virtual instrumentation (VI) is rapidly replacing classical analog as well as digital instrumentation systems owing to the availability of high performance microprocessors based PCs, fast Analog-to-Digital Converters (ADCs) and sophisticated data communication technology. Therefore, investigation of more and more efficient and effective VI based solutions to modern instrumentation problems is one of the main research areas for design engineers. The work presented in this paper is application oriented and thus the contribution of the paper is how to instigate the already known control algorithms in NI LabVIEW. Instead of relying on commercially available expensive hardware, a low-cost self-developed DAQ card is employed. The elaboration of the idea is carried out by designing a VI based DC drive and a thermal system. modeling, PID controller and user-interface development is presented for both examples. The positive results of this study establish the utility of virtual instrumentation especially for control applications.

Sensory systems, such as computer vision, can be used to measure relative robot end-effector positions to derive feedback signals for control of end-effector positioning. The role of vision as the feedback transducer affects closed-loop dynamics, and a visual feedback control strategy is required. Vision-based robot control research has focused on vision processing issues, while control system design has been limited to ad-hoc strategies. We formalize an analytical approach to dynamic robot visual servo control systems by first casting position-based and image-based strategies into classical feedback control structures. The image-based structure represents a new approach to visual servo control, which uses image features (e.g., image areas, and centroids) as feedback control signals, thus eliminating a complex interpretation step (i.e., interpretation of image features to derive world-space coordinates). Image-based control presents formidable engineering problems for controller design, including coupled and nonlinear dynamics, kinematics, and feedback gains, unknown parameters, and measurement noise and delays. A model reference adaptive controller (MRAC) is designed to satisfy these requirements. © 1985 IEEE.

With the accelerated integration of the new generation information technology and manufacturing industry, the performance of production equipment continues to be optimized, evolved and upgraded iteratively. The production equipment model presents a multi-dimensional, multi-level, full life cycle integration development trend, which has become the key to improve the innovative capability and digital management level of production equipment. Aiming at the problems of multiple types of production equipment models, such as complex structure, difficult integration and low application efficiency, this study analyzed the relationship and interaction mechanism among production equipment models from the perspectives of life cycle, hierarchical structure and multi-dimension, and built a production equipment model architecture. Based on the model architecture of production equipment, a general multi-dimensional fusion framework of production equipment models was proposed, which takes the mechanism model as the core. This study can provide reference for the construction, integration and application of production equipment models. © 2023 ACM.

Due to the computational complexity (NP-Complete) of Constraint Programming (CP), several researchers have abandoned its use in robotic research field. In the last decade, as many approaches of real-time constraint handling have been proposed, constraint programming has proved to be a stand-alone technology that can be used in several research fields. Even if mobile robotics is a complex research area, in this paper, we prove that distributed constraint reasoning techniques can be utilized as a very elegant formalism for multi-robot decision making. First, we describe dynamic distributed constraint satisfaction formalism, the new platform architecture "RoboChoc" and specify how decision making can be controlled in multi-robots environment using dynamic communication protocols. Then we provide an example application that illustrates how our platform can be used to solve multi-robot problems using constraint programming techniques.

The F oilfield in the Middle East straddles Iran and Iraq, and the contract block only includes the Iraqi part, structural incompleteness is a difficult problem in oilfield research. Oilfield development and geological modeling also face several other challenges, including complex lithology, many factors affecting reservoir physical property, lack of testing data resulting in great uncertainty in physical property interpretation, and no effective constraints in attribute modeling. In view of these difficulties, a set of fine reservoir geological modeling technology series suitable for trans-boundary and mixed reservoirs are established, including set up virtual wells to complete the structure, multistage facies controlling geological modeling, mixed lithology classification and sedimentary microfacies study, evaluation of effective permeability by dynamic and static combination, conditional constraint saturation modeling. Referring to the structural form of Iranian part of F Oilfield in public data, the virtual wells are reasonably set up, and the incomplete anticline structure is complemented by combining the virtual wells with the structure in the contract area. A two-stage model of lithofacies and reservoir facies is established by using the idea of multistage facies control. The reservoir facies model is established under the constraint of sedimentary facies model to ensure the reasonable distribution of reservoir in space. By using the two-terminal element classification method, the classification standard of mixed reservoir suitable for F oilfield is established, and the research process of sedimentary microfacies in mixing background is formed, which solves the problems of complex rock classification and sedimentary microfacies research, and lays the foundation for the modeling of sedimentary facies and reservoir facies. Effective permeability of single well is evaluated by combining dynamic and static data, and the trend surface of dynamic/static permeabilit

This proposition deals with interoperation of data and security policies in cooperative information systems. We use the agent paradigm for the treatment of distributed programs and perform complex tasks through cooperation and interactions. A combination of two methods - GAIA and AUML - and a set of models are used. Two protocols are defined related to the features of the system: (i) a knowledge management protocol to address interoperability problems between different modes of data representation and security access models and, to generate the matches between these models, (ii) a query resolution protocol using global knowledge. Agents are described in their goals, their interactions, their knowledge by defining their roles for each protocol, including the key role of the security mediator. A prototype is implemented on the JADE platform (Java Agent Development Environment). © 2013 ACM.

A novel 1D approach for the simulation of unsteady reacting flows in diesel exhaust after-treatment systems

引用

ENERGY 2009年第12期34卷 2051-2062页

作者： Piscaglia, F. Ferrari, G. Politecn Milan Dipartimento Energia I-20133 Milan Italy

A new one-dimensional approach, based on the solution of the governing equations for unsteady, reacting and compressible flows has been developed for the simulation of the hydrodynamics, the transient filtration/loading and the catalytic/NO(2)-assisted regeneration occurring in diesel particulate filters (DPF). The model is able to keep track of the chemical compounds, of the amount of soot transported by the flow, and it can estimate the increasing of back-pressure occurring in the exhaust system, due to the permeability variation of the porous wall and to the soot cake building up on the DPF porous surface. Further, a prediction of the oxidation of the deposited particulate induced by the Oxygen (collected in the exhaust gas), by the nitrogen dioxide (NO(2)), by the carbon oxide (CO) and by the hydrocarbons (HC) converted along the diesel oxidation catalysts (DOC) is given. A first validation of the code has been performed by the comparison with the results coming from computational fluid dynamics (CFD) and with experimental measurements published in literature. The proposed model has been included in an engine simulation code, in order to perform a simulation of a complete engine: results coming from an optimization work recently carried out on a 1.9 L JTD turbocharged diesel engine, equipped with a complex after-treatment system, are presented.

To solve the problems of large volume, complex routing and low system precision of space manipulator, the technology of integrative design is presented to realize high-cohesion and low-coupling integrative joint for space manipulator, which integrates permanent magnet synchronous motor, controller, driver, resolver, adaptability design of space environment, routing and joint mechanism and so on into a whole. To realize each component in joint to match exactly each other, all components of integrative joint are simultaneously planned and designed to achieve high-cohesion and low-coupling. This kind of design can eliminate the redundant shells and mount surfaces in traditional joint of space manipulator, which can increase power density and enhance system performance with a simple mechanical interface and standard electrical interface. This paper proposes a novel method to realize dual-redundancy detection for motor rotor and joint positions by installing two resolvers onto motor shaft at the same time, which can also improve position detection precision and noise immunity by difference principle, decrease joint size and simplify joint structure. In addition, the thermal control and isothermal design are adopted to obtain the temperature balance in integrative joint. Experimental results validated the design scheme in this paper, and it showed that studied integrative joint had nice driving performance to meet the requirements of space manipulator at light weight, high rigidity and high precision.
