Guaranteed cost control for multi-sensor networked control systems using historical data

In this paper, the networked control system with multiple physically distributed sensors is considered. The state information of the discrete-time plant with multiple state delays is sent to the controller by communication networks. By setting a sensor scheduling algorithm, the controller receives the measurement from one sensor at each time step. The guaranteed cost state feedback controller is proposed which considers not only the most updated state information, but also the historical information of the state. In addition, according to the sensor scheduling scheme, we design and implement different control gains, i.e., the so-called sensor-dependent controller. A numerical example with multiple sensors in the networked control system is provided to illustrate the effectiveness of the proposed controller design technique.
