Abstract:
In this paper, based on the state-dependent Riccati equation (SDRE) technique, a new method is proposed to design nonlinear observers in a  broadclass of networked control systems. Towards this end, an inequality condition is obtained to detect the time-instants of sending messages from the sensors to the controller. In this way, the data transmission is done in some specific instants and therefore, the proposed method can considerably reduce the information exchange between the sensors and the controller in a nonlinear networked control system. It is also proved that the obtained estimation converges to the system state. Two numerical simulations are worked to illustrate the design procedure and the flexibility of the proposed observer.
