New Compound Fractional Sliding Mode Control and Super-Twisting Control of a MEMS Gyroscope

Abstract This research proposes a new compound fractional sliding mode control (FOSMC) and super-twisting (FOSMC + STC) to microelectromechanical systems gyroscope. A surface has been defined design the proposed controller. The main advantages of FOSMC are its high tracking performance robustness against external perturbation, but creating chattering phenomenon is drawback. By applying (STC) method with FOSMC, eliminated, singularity problem solved, significantly improved. Simulation results validate effectiveness approach.
