Chattering-free uncertain variable structure discrete control system based on disturb compensation

On single-input multi-variable uncertain variable structure control system design issues, in view of both a parameter perturbations and disturbance outside the single-input multi-variable system oscillation problems using the principle of optimal estimate for the disturbance compensation, a new variable structure control programs was proposed to eliminate the system's chattering phenomenon, and improve the system and the transient performance and robustness. The simulation shows that the structure of the algorithm is effective.
