Abstract :
This paper proposes a supervisory control approach for networked control systems with multiple communication delays. The supervisor coordinates the switching among the multi-controllers with respect to the network-induced delays. The control scheme could improve the closed-loop performance in comparison with the conventional scheme using a single robust controller. We demonstrate that the stability of the switched control loop can be analyzed by solving a set of linear matrix inequalities (LMIs). Finally, a numerical example is used to demonstrate the effectiveness of the proposed method.
