The invention provides an angular velocity estimation based self-adaptive fuzzy sliding mode control method, applies the self-adaptive fuzzy sliding mode control method to a micro three-axis gyroscope control system, and can realize the trajectory tracking control and parameter estimation of a micro gyroscope system. According to the self-adaptive fuzzy sliding mode control method, a controller is designed on the basis the state-space equation of a micro gyroscope. Firstly, on the basis of the sliding mode controller, a novel self-adaptive identification method is designed, and the angular velocity of the micro gyroscope and the estimated valves of other systematic parameters are updated on line and in real time; besides, a fixed gain in a sliding mode control toggle item is adjusted by virtue of a self-adaptive fuzzy system, and fuzzy approximation is performed to the upper bound of the fixed gain, so that a chattering phenomenon arising in sliding mode control can be reduced. Through the adoption of the self-adaptive fuzzy sliding mode control method, a favorable tracking performance can be obtained, and the self-adaptive fuzzy sliding mode control method has robustness in parameter variation and external disturbance.
