Abstract :
In this paper, an adaptive fuzzy controller with supervisory compensator is proposed for a MEMS gyroscope. The parameters of the membership functions are determined on-line by a Lyapunov based adaptive controller. A fuzzy controller is employed to approximate and compensate the unknown system nonlinearities. A supervisory compensator is adopted to guarantee the stability of the closed-loop system and boundedness of the state variables. Numerical simulations show the satisfactory performance and robustness property in the presence of external disturbances system using the proposed fuzzy controller with supervisory compensator.
