Takagi-Sugeno Fuzzy System based Stable Direct Adaptive Control of Nonlinear Systems

Abstract

This paper proposes a novel idea for stable direct adaptive control of nonlinear systems using Lyapunov function with fuzzy approach.Stable direct adaptive control law consists of an ideal control, and a sliding mode control.Sliding mode controller is used to ensure the stability of Lyapunov function.Stability of direct adaptive control law is tested on two nonlinear systems.Non linear systems analyzed are ball beam system and cart pole system.A computer simulation is performed on nonlinear systems by using MATLAB.
