The compensation of message dropout in the Internet-based telecontrol system

The message dropout will degrade the control performance in the Internet-based telecontrol system. The switched controller is proposed to compensate the network delay and message dropout. It changes among the different structures by inspecting the sampling cases in the forward and feedback paths. The theory analysis shows that the stability and steady-state error will be maintained, but the transient time will increase. The four experiments prove that conclusion.
