Predictive control of networked systems with communication delays

This paper studies the problem of predictive output feedback control for networked control systems with random communication delays. A networked predictive control scheme is employed to compensate for random communication delays, which mainly consists of the control prediction generator and network delay compensator. Furthermore, a new strategy of designing the time-varying predictive controller with mixed random delays for networked systems is proposed. Then the system can be formulated as a Markovian jump system. New techniques are presented to deal with the distributed delay in the discrete-time domain. Based on analysis of closed-loop networked predictive control systems, the designed predictive time-varying output feedback controller can achieve the desired control performance and also guarantee system stability. Simulation examples demonstrate the compensation for random communication delays and data loss in networked systems using the proposed predictive controller design strategy.
