Abstract:

This paper presents a robust adaptive trajectory linearization control (RATLC) based on T-S fuzzy system. The unknown disturbances and uncertainties are estimated by T-S fuzzy system, and a robust adaptive control law is designed using Lyapunov theory. Whether the dimensions of the system states and the rules of the fuzzy system are large or little, there are only two parameters adjusting on line. The uniform ultimate boundedness of all signals of the composite closedloop system is proved by theory analysis.
