This paper addresses the tolerance issue of intermittent controller faults in the system level. A control system with intermittent faults is modeled by a stochastic hybrid system, whose stability is shown equivalent to the fault tolerability of the original system. A “global dissipativity” concept is introduced for the hybrid system to derive its stability condition, which can be checked easily via the proposed “gain technique”. Our results show that it may not be necessary to apply the fault tolerant scheme in spite of intermittent faults. A spacecraft attitude control example is taken to illustrate the efficiency of the proposed method.
