Abstract :
This paper presents a novel design of adaptive sliding mode observer. An adaptive sliding mode observer with a proportional and integral sliding surface is derived and the stability condition of the closed-loop system is established. The proposed adaptive sliding mode observer could reconstruct the unmeasured states and estimate unknown system parameters in real time despite parameter variations and external disturbance. The numerical simulation of MEMS gyroscope m is investigated to verify the effectiveness of the proposed control scheme.
