Abstract
This paper studies the discounted-cost linear quadratic output regulator design for a class of switched linear systems by designing the controllers for each subsystem and the switching signal. The distinguishing feature of the proposed method is that the designed discounted-cost linear quadratic output regulator will achieve not only the desired optimization index, but also the exponentially convergent of the state of the closed-loop switched systems. The embedding transformation technique is used to transform the studied problem of switched system into a traditional optimal control problem. Then, it is shown the bang-bang-type solution of the embedded optimal control problem is the optimal solution to the original problems for both the finite horizon and infinite horizon. Both the switching signal and the controller for each subsystem are designed simultaneously. An example of boost converter is shown to illustrate the effectiveness of the proposed result.
