A Kind of Sliding Mode Control Strategy Based on Delay Estimation Online for Networked Control System with Stochastic Less Delay

摘要

Aiming at the NCS with stochastic less delay, a discrete sliding mode control strategy based on delay estimation on-line is presented. The delay iterative measuring and pretest parameters-based estimating methods are adopted, and a sliding mode controller with loop-delay estimation online is designed to overcome the adverse influence caused by time-varying delay. Simulation study indicates that the above-mentioned algorithm has good control performance and also avoids large numbers of on-line mean and variant operations in normal stochastic control.
