Chattering-Free Sliding Mode Control for Networked Control System with Time Delay and Packet Dropout Based on a New Compensation Strategy

Abstract EN

This paper addresses the sliding mode control problem for a class of networked control systems with long time delay and consecutive packet dropout.

A new modeling method is proposed, through which time delay and packet dropout are modeled in a unified model described by one Markov chain.

To avoid the chattering problem of classic reaching law, a new chattering-free reaching law is proposed.

Then with a focus on the problem that controller-actuator channel network condition cannot be foreseen by the controller, a new compensation strategy is proposed, which can effectively compensate for the effect of time delay and packet dropout in controller-actuator channel.

Finally, a simulation example is presented to demonstrate the effectiveness of the proposed approach.
