Robust Linear Parameter-Varying State-Observer for an Induction Motor

This paper addresses observation and estimation of some states of an induction motor with parameter uncertainty. State observation is an important step in controller synthesis for systems which measurement of all states is not possible or affordable. At the first, a linear parameter varying (LPV) model is presented for induction motor and then via extending LPV observers for uncertain systems, a robust LPV observer is designed for induction motor. In the proposed method, the immeasurable parameters are considered as uncertainty. The results of simulation verify the validation of designed observer
