Time-stamp based state prediction control approach to a class of networked control systems

A time-stamp based state prediction control approach was presented for compensating time-delay in the networked control system (NCS). Firstly, a time-stamp based algorithm of measuring the time-delay in NCS was studied and the state prediction based time-delay compensation control was implemented to the system. The state prediction control approach to establishing an approximate model to object states in the controller and actuator time-driven was proposed. A state prediction controller was designed to make the system achieve prediction control. The necessary and sufficient conditions for stabilizing the system were deduced. Finally, a numerical example was given, and the state curve of prediction controller was simulated. The results prove the validity of the proposed approach.
