Abstract: This paper investigates the design problem of the event-triggered model predictive control for networked control system (NCS), in which the signals will be quantized when transmitted from the sensor to controller and controller to actuator. The networked model with event generator is established and the event-triggered scheme is designed. And then, a model predictive control method is presented. The stability condition for closed-loop system is derived. Finally, a numerical simulation is given to illustrate the effectiveness of the proposed scheme.
