Analysis and Design of rotor MRAS Speed Sensorless with a Novel Approach

Abstract : In present work a modified MRAS for induction motors is presented. Associated with vector control, the speed estimation performances are improved especially at low speed. Lyapunov theory based controllers is used to design the controllers of the vector control. Robustness against the parameter variations and the low speeds mode is proven. The experimental tests are conducted using dSPACE DS1104.
