Two channel event-triggering communication schemes for networked control systems

This paper is concerned with event-triggered controller design for networked control systems. At first, novel model-based event-triggered transmission strategies for both the sensor-to-controller and the controller to actuator channels are proposed, which are capable of reducing the communication bandwidth utilization, while preserving the desired control performance. Second, considering the effect of the network transmission delay, a newly delay system model for the analysis is firstly constructed. Third, based on our newly proposed model, criteria for stability and criteria for co-designing both the feedback gain and the trigger parameters are derived. Finally, a numerical example is given to demonstrate the effectiveness of the proposed method.
