Abstract	In this paper a hybrid sensorless speed method for Interior Permanent-Magnet Synchronous Motors (IPMSM) is proposed. This method works efficiently at very low up to rated speed. An adaptive full-order observer has been implemented in medium and high speeds using fictitious permanent-magnet model. At standstill and low speeds a signal injection method is augmented to an adaptive observer for better estimation. Adopted signal injection method superimposes a pulsating voltage on the voltage reference in the stator reference frame. In order to achieve good performance, a Maximum Torque Per Ampere (MTPA) vector controller is incorporated with a synchronous frame decoupling scheme. Since in applied control method the motor parameters are widely utilized, a Recursive Least Square algorithm (RLS) has been applied to online parameter identification. Finally, in order to evaluate the performance of the proposed method, a comprehensive set of simulations were performed.
