Superior performance of switched fuzzy control systems: An overview and simulation experiments

Abstract

This article gives a brief overview of the basic notions of switched fuzzy systems, their model construction and stability analysis, followed by the proposed concepts for building simulation algorithms for this type of systems. Using these concepts we have shown the whole process of modelling, stability analysis and design of stabilizing switching fuzzy logic controllers for the hovercraftvehicle as a typical nonholonomic system. MATLAB Simulator (Simulink model) and special MATLAB functions for the switching fuzzy controller of the hovercraft vehicle, along with the numerous simulation results, verify the correctness of the proposed concepts. Using this typical nonholonomic system we have also explored the good performance of switched fuzzy systems in comparison to the ordinary T-S fuzzy systems.
