A Optimal Guaranteed Cost Control of Networked Multi-Rate System

doi:10.16183/j.cnki.jsjtu.2018.01.018

Abstract

Abstract: In multi-rate networked control system (NCS), the sampling period of sensor, controller and actuator shows the characteristics of asynchronous sampling uniformity. The whole system is no longer a single-rate sampling mode, and it is more suitable for the essential characteristics of NCS and control requirements. A networked multi-rate input control system with network-induced time-delay and output prediction is illustrated in this paper. A dynamic output feedback controller is designed to obtain the optimal guaranteed cost control of the system, and the stability of this closed-loop control system is proved by linear matrix inequality (LMI) method. Finally, a numerical simulation is given to demonstrate the effectiveness of the proposed control system.

Key words: networked control system (NCS); multi-rate sampling; network-induced time-delay; output prediction; optimal guaranteed cost control
