摘要：
A model based Fault Diagnosis algorithm for a class of nonlinear systems is proposed and applied to the DC/DC buck converter-inverter-DC motor system. With the proposed algorithm faults in the sensor that measures the current flowing through the inductor of the buck converter, mechanical faults in the rotor and motor bearings that affect the viscous friction and faults in the transistor that regulates the output voltage of the buck converter are detected and isolated; these faults are modeled as sensor, system and actuator respectively. Faults in sensor and actuator are modeled as additive and the mechanical faults as multiplicative.
