Predictive controller design for networked systems

摘要

This thesis considered the analysis and design of networked control systems with the communication delay and data loss, which are responsible for degradation of the control performance. Predictive control strategy is applied to compensate the communication delay and data loss in the NCS. The stability and the system performance of the close-loop networked control system are analyzed. Also, this control strategy is applied to a DC servo control system with communication delay and data packet loss. The stability of the closed-loop networked predictive control system has been analyzed and the comparison with other existing networked control methods like H_∞ control [20] , Networked predictive control for random network delays in both forward and feedback channels [21] and Model-based control [22].
