Abstract :
In this paper, fault detection and isolation of a DC motor is discussed. Dynamic space parity approach is used to detect faults. Based on structural residual method, the theoretical symptoms matrix is established. The later is compared to an experimental one to isolate the faults. The validity and usefulness of the fault detection and isolation algorithms are thoroughly verified with experiments on 1kw DC motor using a dSpace system with DS1104 controller board based on digital signal processor (DSP) TMS320F240.
