Limit-bandwidth networked predictive control of systems with communication delay and data loss in the feedback channel

Abstract

This paper discusses the networked predictive control with communication delay and data loss in feedback channel under limit-bandwidth through a single value. A networked predictive control scheme is used to actively compensate for the communication delay and data loss. Based on the analysis of the closed-loop networked predictive control systems, a design strategy and detail steps is proposed. The designed predictive controller can achieve the desired control performance and also guarantee the system stability. A numerical example demonstrates that the proposed networked predictive control scheme can compensate the communication delay and data loss actively in feedback channel under limit-bandwidth.
