Variable Structure Control for Multi-input Discrete Systems with Control Delay
Mi Yang · Kongzhi yu juece · 2006
The problem of variable structure control for multi-input linear discrete systems with control delay is considered.The original discrete system with control delay is simplified to a linear discrete system without time-delay,and a novel chattering-free variable structure control strategy for the discrete system is developed.The sliding mode is attained by this control law which drives the system to reach and remain on the intersection of a set of prescribed sliding manifolds in finite time.The switching surface will not be passed through,so the chattering behaviors will not occur.The simulation results verify the validity of the proposed approach.
