Abstract: To study networked control system with multi-rate input sampling, transforms the system into a single-rate sampling system by introducing lifting technique. Adopting model-based control scheme, state feedback control and stability of the system under different transmission policies are studied. Necessary and sufficient conditions for system to be globally exponentially stable are derived. Then, the model errors influence on the maximum communication interval is investigated. Simulation examples are used throughout to illustrate the main results. It is to be noted that the smaller the model error, the larger the maximum transmitting time.
