Abstract

To improve reliability some systems adopt double redundancy; however, some failure conditions may prevent the normal operation of the machine or the machine to reach a safe state. The method proposed in this paper allows the normal operation of the system even in a fault condition of the control unit. The signals resulting from the parallel execution of code are modulated to a higher frequency and decoupled from each control stage using two capacitors; the information is then demodulated to obtain the control signal, either in the case of one or two branches working in the control unit.
