Adaptive Fuzzy Control of MEMS Gyroscope Using Global Fast Terminal Sliding Mode Approach

This paper deals with the adaptive fuzzy sliding mode control problem for MEMS Gyroscope system via the global fast terminal sliding mode approach. A global fast terminal sliding-mode controller is designed to guarantee that the system can reach the sliding surface and converge to equilibrium point in a shorter finite time from any initial state surface. Furthermore, an adaptive fuzzy control is introduced to approximate the model uncertainties and external disturbances. The chattering caused by the sliding mode control is weakened as well. The stability analysis and tracking performance of the gyroscope system are verified by Lyapunov stability theory. Simulation results are provided to demonstrate the effectiveness of the proposed control schemes.
