Adaptive Super-Twisting Sliding Mode Control for Micro Gyroscope Using Fuzzy Sliding Gain

This article studies a novel adaptive Super-Twisting sliding mode control scheme for a micro gyroscope using fuzzy sliding gain. Firstly, an adaptive algorithm is used to estimate the unknown parameters of micro gyroscope. Secondly, this paper utilizes the universal approximation characteristic of the fuzzy system to estimate the gain of the Super -Twisting sliding mode controller and identify the gain of the controller on line, realizing the adaptive adjustment of the controller parameters. The simulation results verify the superiority of the proposed approach.
