Switched fuzzy control systems: Exploring the performance in applications

Abstract

In this paper we propose a concept for building simulation algorithms for switched fuzzy control systems. Using these concepts we have shown the whole process of modeling, stability analysis and design of stabilizing switched fuzzy logic controllers for the hovercraft-vehicle, as a typical nonholonomic system. Using this typical nonholonomic system (the system is subject to constraints involving both, the position and velocity, whereupon it can not be stabilized by any continuous feedback control law) we have also explored the good performance of switched fuzzy systems in comparison to the ordinary T-S fuzzy systems. MATLAB Simulator (Simulink model) and special MATLAB functions for the switched fuzzy controller of the hovercraft vehicle, along with the numerous simulation results, verify the correctness of the proposed concepts.
