Abstract

PURPOSE:To ensure to detect failures from the output of the control circuit without giving effect on the control output signal, by applying the failure detection signal to the input of each control circuit with inversion of polarity, in the control circuit constituting the redundancy circuit. CONSTITUTION:The failure detection signal E from the signal generator 14 and the feedback signal fL from the control variable 4 are summed 12, 13 and fed to the first and the second control circuits 1a, 1b of redundant constitution. The signal E is fed to one adder 12 with inversion 15. Further, the output of the control circuits 1a, 1b is processed at the coefficient circuit 17 and fed to the control variable as a signal not including the failure detection signal E and the failure of each control circuit is judged at the failure detector 16.
