Abstract :
This paper presents frequency response methods to analyse the stability of multivariable fuzzy control systems. Three different techniques of decreasing conservatism and increasing computational complexity are considered. Matlab functions to implement these techniques have been programmed. The techniques are compared when applied to the analysis of a multivariable fuzzy control system with pure delays
