Kalman filter based fault detection of dual motor systems

Fault detection of a class of dual motor systems is discussed in this paper. A linear dual motor systems with sensor faults and actuator faults as well as random noise are modeled, and a Kalman filter based fault detection scheme is proposed. In the designed fault detection scheme, a Kalman filter based residual generator is constructed to generate the residual signal, and then an evaluation function is used to provide the fault decision, also a threshold is designed to detect the occurrence of faults. Finally, a simulation example is given to show the applicability and effectiveness of the proposed fault detection approach.
