A quasi linear parameter varying approach to robust control of an Induction machine

The Induction Machine employing vector control is an unbeatable solution in high performance economical industrial servo drive applications. We present in this paper a high performance and robust controller applied to the induction motor. The proposed solution is based on a quasi Parameter Varying Approach framework to overcome the high non-linearity of dynamic model in rotating d,q frame. The LPV framework has been widely and successfully applied to robust nonlinear control to provide stability under model uncertainties. The numerical simulation results obtained show benefits of proposed solution in electrical drive systems.
