ICANNGA'07 tutorial on

Intelligent Control Systems: An Engineering Approach

Stanisław H. Żak

Purdue University

School of Electrical and Computer Engineering

Purdue University, West Lafayette, IN

USA

 

A major problem that has been facing control engineers is the growing gap between “real world” control problems and the theory for analysis and design of linear control systems. Design techniques based on the linear system theory have difficulties with accommodating nonlinear effects and modeling uncertainties. The objective of this tutorial is to present the theory and design of intelligent controllers and observers. The emphasis will be on design in order to show how intelligent control system theory fits into practical applications.

 

Participants will learn first the ingredients of intelligent controllers that include adaptation, learning, fuzzy logic, neural networks, and genetic algorithms. Then, participants will learn how to combine these ingredients to obtain sensory interactive control structures incorporating cognitive characteristics to emulate learning behavior with a capacity for performance or parameter adaptation. The content will include:

  • Formulation of the control problem

  • Mathematical modeling  of dynamical systems versus linguistic modeling of dynamical systems

  • Adaptation

  • Sliding mode control

  • Synergetic control

  • Fuzzy logic control

  • Neural network based controllers

  • Genetic algorithms

  • Neural observers

  • Lyapunov stability theorem and Barbalat’s lemma as tools for constructing intelligent controllers and observers

  • Combined controller-observer compensators

  • Genetic algorithm based sliding mode adaptive neural fuzzy control architectures

  • Model-based fault detection and isolation

  • Example design - intelligent control of induction motor.

 

Prof. Stanisław H. Żak received his Ph.D. degree from the Warsaw University of Technology (Politechnika Warszawska) in 1977. He was an Assistant Professor in the Institute of Control and Industrial Electronics (ISEP), Warsaw University of Technology, from 1977 until 1980. From 1980 until 1983, he was a Visiting Assistant Professor in the Department of Electrical Engineering, University of Minnesota in Minneapolis. In 1983 he joined the School of Electrical and Computer Engineering at Purdue University in West Lafayette, IN, where he is now a Professor. He has worked in various areas of control, optimization, fuzzy systems, and neural networks. He is a co-author with T. Kaczorek and K. M. Przyłuski of Topics in the Analysis of Linear Dynamical Systems published in 1984 by the Polish Scientific Publishers (PWN) in Warsaw, Poland. He is also a co-author with E. K. P. Chong of An Introduction to Optimization whose second edition was published in 2001 by Wiley-Interscience. He is the author of Systems and Control, published in 2003 by Oxford University Press. Dr. Żak is a past Associate Editor of Dynamics and Control and the IEEE Transactions on Neural Networks.
