Event-triggered and Optimal Control Co-design for Networked System With Fragile Communication Links

For a networked control system with both packet loss and Gaussian white noise disturbances in the sensor-controller and controller-actuator network paths, we propose a linear quadratic Gaussian optimal control method based on event-triggering. Considering the joint design problem of optimal event-triggered and optimal control, we firstly deduce an event-triggered quadratic optimal cost function. Secondly, we use a dynamic programming method to carry out the optimal co-controller design for the established mathematical model. Finally, we verify the effectiveness of the proposed control strategy through intelligent cart trajectory tracking simulation experiments on MATLAB platform.
