PROBLEM TO BE SOLVED: To inexpensively constitute a redundant processing system with sufficient reliability by having no part to be a single fault point in a system. SOLUTION: The redundant information processing system to control an actuator 5 based on a signal from a sensor 4 is provided with a processor part 2 in which each of processors 1A to 1C decides what command signal from other processors is validated by a logical decision, for example, majority decision, outputs command transmission signals according to priority, outputs control information stopping signals to the processors except the one to be validated when command signals of two or more processors including the applicable processor are validated, outputs no command transmission signal and outputs no control information stop signal to other processors when the command signals of the processor except the applicable processor are validated. The system is also provided with an interface part 3 to control output of the command signal to the actuator by the number of inputted control information stop signals from other processors.
