Abstract :
Deals with the design of a nonlinear fault tolerant controller for an induction motor. We show how an indirect field oriented controller can be modified in order to compensate the side-effects arising in presence of electrical and mechanical faults and, so doing, also to detect the occurrence of the fault. To this end we follow the nonlinear regulation theory, namely we design a nonlinear controller embedding an internal model of the fault which automatically activates when spurious harmonic currents arise
