Switching Surface Design for Periodically Operated Discretely Controlled ContinuousSystems

摘要

Discretely controlled continuous systems (DCCS) represent an important class of hybrid systems, in which a continuous process is regulated by a discrete controller. The paper introduces a novel model-based design procedure for periodically operated DCCS with the objective to produce a periodic stationary operation. The method exploits an equivalence to periodic control systems to obtain an event-driven switching strategy that locally stabilizes a predetermined limit cycle and enforces a desired transient behavior. In contrast to earlier results, the controller responds to deviations without a dead time.
