HARDWARE FAULT DETECTION FOR FEEDBACK CONTROL SYSTEMS IN AUTONOMOUS MACHINE APPLICATIONS

Abstract:

Systems and methods for detecting hardware faults in computer-based feedback control systems. Multiple instances of the system control program(s) are run on system processors. System sensor data are input to each instance, and the control commands output by each instance are compared. As instantiations of the same programs receive largely the same sensor data, differences between output commands may indicate the presence of one or more hardware faults.
