Optimal Output Feedback Control and Stabilization for NCSs with Packet Dropout and Delay: TCP Case

摘要

This paper considers the output feedback control and stabilization problems for network control systems (NCSs) with packet dropout and input delay,and the TCP (transmission control protocol) case is mainly investigated.Specifically,whether the control signal is lost can be acknowledged by the receiver in the NCSs.The main contributions are:1) For the finite horizon case,the "optimal"output feedback control is derived by using the dynamic programming approach,and it is noted that the separation principle holds for the considered situation;2) For the infinite horizon case,for the first time,the necessary and sufficient stabilization conditions are derived for NCSs with packet dropout and delay.
