ROBUST PID DECENTRALIZED controlLER DESIGN USING LMI

IFAC Proceedings Volumes 2006年第14期39卷 53-58页

作者： Danica Rosinová Vojtech Veselý Department of Automatic Control Systems Slovak University of Technology Faculty of Electrical Engineering and IT Bratislava Slovakia

The new LMI based method for robust stability analysis for linear uncertain system with PID controller is proposed. The general constrained structure of controller matrix is considered appropriate for both output feedback and decentralized control and the respective guaranteed cost control design scheme is presented. The sufficient robust stability condition is developed for extended quadratic performance index including first derivative of the state vector to damp oscillations. The obtained stability condition is formulated for parameter-dependent Lyapunov function.

This paper considers the design of robust servo system for accurate tracking of complex referent signals in the presence of internal and external disturbances. Discrete-time sliding mode tracking controller is employed in servo-system design. In order to improve tracking accuracy, application of active disturbance estimator is suggested. The same sliding mode controller, designed for reference tracking of nominal system, is identically implemented in the control subsystem within the estimator. The overall servo-system exhibits high tracking accuracy under action of parameter uncertainties and external disturbances. Experimental results confirm the effectiveness of the proposed servo-system structure

This paper presents the main features of a sugar factory training simulator currently used for control room operators training. This simulator is based on a realistic distributed real time simulation of the whole factory and in a mimic of the control system. It allows the familiarization of the operators with the process and control system as well as with the process information that they use in the real plant. The main aims of the simulator are: (i) to guarantee operators knowledge of the process, and its control system;(ii) to test potentially dangerous situations and (iii) to identify possible problems sources and learn to correct them.

An adaptive output feedback neurofuzzy controller

引用

Journal of engineering and Applied Science 2006年第4期53卷 503-521页

作者： Asham, A.D. Badr, R.I. Sultan, M.A. Elmaady Cairo Egypt Faculty of Engineering Cairo University Giza Egypt Department of Automatic Control Faculty of Engineering Cairo University Giza Egypt

An adaptive neurofuzzy controller is developed, which is fed with the outputs of the controlled system avoiding the measurement of the system inaccessible states. This controller is based on a neurofuzzy model, which is adaptively built online. The proposed technique is used to drive nonlinear SISO systems to follow certain linear reference models. An example is given to demonstrate the applicability of the proposed technique.

Robots are complex mechatronics systems where several electric drives are employed to control the movement of articulated structures. In industrial environments they must perform tasks with rapidity and accuracy in order to produce goods and services with minimal production time. These procedures require the use of flexible robots which can act in a large workspace, thus subjected to important parameters variations and nonlinear dynamics effects. This paper investigates the fractional order dynamics during the evolution of trajectories of three robotic joints, considering the complete system dynamics. Copyright © 2006 IFAC.

作者： H. R. Karimi P. J. Maralani B. Lohmann B. Moshiri Institute of Automatic Control Technical University Munich Munich Germany Control and Intelligent Processing Center of Excellence Department of Electrical and ComputerEngineering Faculty of Engineering University of Tehran Tehran Iran

Using Haar wavelets, a computational method is presented to determine the piecewise constant feedback controls for a finite-time linear optimal control problem of a time-varying state-delayed system. The method is simple and computationally advantageous. The approximated optimal trajectory and optimal control are calculated using Haar wavelet integral operational matrix, Haar wavelet product operational matrix and Haar wavelet delay operational matrix. An illustrative example is included to demonstrate the validity and applicability of the technique

This paper deals with the parity based fault estimation for nonlinear systems modelled by Takagi-Sugeno (TS) fuzzy models. In this paper, the parity space approach for linear systems is generalized to TS fuzzy systems, and power spectra of the faults are incorporated into the design procedure. The design procedure is given in terms of a family of linear matrix inequalities (LMIs). Finally, a numerical example is given to illustrate the effectiveness of the proposed design techniques

This paper presents EDUSCA, an EDUcational SCAda with OPC data access. EDUSCA was specially designed for automatic control education, research and operator training purposes. The developed system takes advantage of the facilities offered by the OPC communication architecture. The system allows the students to face real practical problems, could be used to train operators in plant supervision and also allows the implementation of research functionalities. Their main advantages of EDUSCA are: (i) it can be connected to any plant whenever it includes OPC communications;(ii) it is free of licenses, thus it can be installed in many computers as necessary;(iii) it can be adapted to each application requirements and (iv) it allows the implementation of a diverse set of functionalities, as for example, control algorithms.

In this paper, the results from a joint industry-academia project in industrial robotic force control are presented. The extension and implementation of an external sensor system for an industrial robot system, which can be used for high-bandwidth force control, are described. Results from two industrial applications using the system are presented, a stub grinding application using a new compliant grinding end-effector integrated with the robot control system, and a deburring application with a stiff tool requiring high-bandwidth force control in six degrees of freedom. Using the system an easily reconfigurable control structure was achieved, which was able to control contact forces with a sampling bandwidth of an order of magnitude higher than for conventional robot controllers
