This paper presents a simple corrective control scheme for overcoming state transition faults occurring in the operation of asynchronous sequential circuits. The proposed controller is static, as it does not need any memory in its design so as to minimize the controller size. We address the existence condition and design procedures for static corrective controllers that invalidate state transition...
Reachability and state recovery for switched asynchronous sequential machines are investigated in this paper. The considered switched asynchronous machine is exposed to the adverse effect of adversarial inputs. The main objective is to design a state feedback controller so that the switched machine can recover the original state after going through unauthorized state transitions by faults. We propose...
We address fault diagnosis and tolerance in dynamics of asynchronous sequential machines based on corrective control theory. The controlled asynchronous machine has input/state type where the present state is given as the output value. We consider a kind of intermittent faults that cause unauthorized state transitions to the machine, and that persist for finite time after the initial occurrence. Not...
