Adaptive Control of Induction Motor Under Magnetic Saturation with Uncertain Rotor Resistance and Unknown Load Torque with Stator Currents and Fluxes Measurements

Abstract

The problem of controlling the induction motor pi-model with magnetic saturation is considered. An adaptive controller is developed under the assumption of measurable stator fluxes but unknown rotor resistance, and load torque. All the unknown parameters are assumed slowly varying and are estimated online by the controller. Simulation results are provided for illustration
