Coordinated static control of asynchronous sequential machines

This paper considers static corrective control of asynchronous sequential machines (ASMs). While static corrective controllers are more efficient than dynamics ones as their implementation needs no memory elements, they have restrictive existence conditions in association with transient states. To alleviate this drawback, we propose a framework of coordinated static control for ASMs. A number of single static controllers are designed to achieve local objectives and the coordinator selects the active controller among them based on the external input and state feedback so that the overall behavior of the closed-loop system matches that of a reference model. Compared with previous static controllers, the existence condition is much improved with mild degradation of design complexity. (C) 2019 Elsevier Ltd. All rights reserved.
