Fuzzy direct adaptive sliding mode control of interconnected large-scale systems

Abstract

Fuzzy direct adaptive sliding mode control design for a class of interconnected large-scale nonlinear systems with unknown functions has been resolved. It makes use of the fuzzy control method via fuzzy logic approximation with fuzzy sliding mode control to approximate the ideal controller synthesised. Fuzzy sliding mode control is introduced to attenuate the fuzzy approximation errors. The (sub)system parameters are being regulated on-line by adaptive laws and stabilised by virtue of Lyapunov's second method applied.
