Adaptive Finite-Time Disturbance Observer Based Sliding Mode Control for Dual-Motor Driving System

This paper investigates a precise tracking control method based on an adaptive disturbance observer for the dual-motor driving system. The unknown matched disturbance is fully considered and estimated in this paper, and the estimation error is proven to be finite-time convergent. A sliding mode cont...
