Patent ID: 7680034

Claim:
A redundant control system for controlling an electromechanical system, comprising: a first processor having a control algorithm and state variables resident thereon, said first processor generating an output signal based on said control algorithm, said state variables, and an input signal from the electromechanical system; a second processor having said control algorithm and said state variables resident thereon, said second processor generating said output signal based on said control algorithm, said state variables, and said input signal; a communication node; a first communication channel communicating said input signal and said output signal between said first processor and said communication node; a second communication channel communicating said input signal and said output signal between said second processor and said communication node; and a signal selector communicating either said output signal from said first processor or said second processor to the electromechanical system, wherein said signal selector randomly selects between said output signal from said first processor and said output signal from said second processor.
