Abstract

The paper discusses the problem of speed and load torque estimation for the induction motor drive. Estimation is done considering that the motor fluxes in the stationary frame are available - these have been obtained using a Voltage Model Observer. With known fluxes, the paper designs a sliding mode observer that estimates both the speed and load torque. The observer is designed using an extended model of the motor. The method uses a different approach and is a significant improvement over the classic Model Reference Adaptive System (MRAS) method (which only estimates the speed). Simulations show that, owing to the sliding mode high-gain feedback, the speed estimate is robust and accurate both at steady-state and during transient; the estimate of the load torque is also accurate.
