Nonlinear control with flux observer for a singularly perturbed induction motor

This paper provides a feedback composite control with nonlinear sliding-mode flux observer for an induction motor using singular perturbation methods. This feedback is composed of slow and fast parts. The authors prove the stability of the closed-loop system with observer. This decomposition simplifies the control scheme which is computed separately on the basis of two subsystems (slow and fast). The control of an induction motor is considered as a case study.<>
