| Title: | Optimal and stable fuzzy controllers for nonlinear systems subject to parameter uncertainties using genetic algorithm | Authors: | Lam, HK Ling, SH Leung, FHF Tam, PKS |
Issue Date: | 2001 | Source: | The 10th IEEE International Conference on Fuzzy Systems : meeting the grand challenge : machines that serve people : The University of Melbourne, Australia, December, 2001, Sunday 2nd to Wednesday 5th, p. 908-911 | Abstract: | This paper tackles the control problem of nonlinear systems subject to parameter uncertainties based on a fuzzy logic approach and the genetic algorithm (GA). In order to achieve a stable controller, TSK fuzzy plant model is employed to describe the dynamics of the uncertain nonlinear plant. A fuzzy controller and the corresponding stability conditions will be derived. The parameters of the fuzzy controller and the solution to the stability conditions are determined using GA. In order to obtain the optimal performance, the membership functions of the fuzzy controller are obtained automatically by minimizing a defined fitness function using GA. | Keywords: | Control system synthesis Fuzzy sets Genetic algorithms Mathematical models Matrix algebra Membership functions Nonlinear control systems Optimal control systems Optimization Parameter estimation System stability Uncertain systems |
