Corrective control can compensate for the stable-state behavior of asynchronous sequential machines (ASMs) in a desirable way. This paper presents fault tolerant corrective control for a class of ASMs where output burst, a quick succession of output characters produced along asynchronous transitions, is given as output feedback. The considered ASM is vulnerable to transient faults that may occur during transient transitions of the machine, or in non-fundamental mode. Compared with the prior work on those faults occurring in fundamental mode, the control objective and the reachability conditions for fault recovery are more restrictive in the case of non-fundamental mode. Based on corrective control theory, we address a scheme of fault diagnosis and fault tolerant control for the closed-loop system to overcome every transient fault causing unauthorized state transitions. An illustrative example is provided to validate the synthesis procedure of the proposed burst-feedback corrective control scheme.

校正控制可以以理想的方式补偿异步顺序机（ASM）的稳态行为。本文提出了针对一类ASM的容错校正控制，其中输出突发（沿异步过渡产生的一系列快速输出字符）作为输出反馈给出。所考虑的ASM容易受到瞬态故障的影响，这些瞬态故障可能在机器的瞬态过渡期间或在非基本模式下发生。与先前针对那些在基本模式下发生的故障的工作相比，在非基本模式下，控制目标和故障恢复的可达性条件受到更大的限制。基于纠正控制理论，我们针对闭环系统提出了一种故障诊断和容错控制方案，以克服引起非授权状态转换的每一个瞬态故障。提供了说明性示例以验证所提出的突发反馈校正控制方案的合成过程。
