This article presents a reconfiguration strategy for the corrective controller achieving model matching control of an input/state asynchronous sequential machine (ASM). The considered controller is vulnerable to permanent faults that degenerate a subset of the controller's states. If the controller has a certain amount of redundancy in terms of its states, one can build a reconfiguration scheme in which the functionality of degenerated states is taken over by supplementary states. The proposed reconfiguration scheme is superior to conventional methods of fault tolerance with hardware redundancy since the required number of redundant states is much smaller. Hardware experiments on field-programmable gate array (FPGA) circuits are provided to validate the applicability of the proposed scheme. The present study serves as the first research report on the reconfigurable corrective controller.
本文提出了一种用于校正控制器的重新配置策略，该策略可实现输入/状态异步顺序机（ASM）的模型匹配控制。所考虑的控制器容易受到永久性故障的影响，这些故障会使控制器的一部分状态退化。如果控制器在其状态方面具有一定数量的冗余，则可以构建一种重新配置方案，其中退化状态的功能由补充状态接管。由于所需的冗余状态数量要少得多，因此所提出的重新配置方案优于具有硬件冗余的传统容错方法。提供了现场可编程门阵列（FPGA）电路上的硬件实验，以验证所提出方案的适用性。本研究是关于可重新配置校正控制器的第一份研究报告。
