Abstract

To achieve required performance of networked control system, this paper proposes an active compensation method for long time delay and packet loss. The controller predicts multi-step future control inputs based on optimization algorithm. This strategy has less conservativeness than others because that the state feedback gain is not fixed, but a variable value depending on feedback delay. The compensator located in actuator side actively compensates the time delay and data packet loss. According the strategy, the rule is established for the selection of data packet and control input, the closed-loop system is modeled as a switched system. The simulated results confirm the analytical results given in this paper.
