### Abstract

(PMSM) requires the absolute position information to be

estimated from the motor currents and voltages. Conventional

model-based estimation algorithm is effective at medium and

high-speed operation but performs poorly at low and zero speed

operation due to small value of motor currents and voltages

which then leads to low SNR values. This paper presents a hybrid

rotor position estimation algorithm over a wide speed range. At

low speed, a new compensated high frequency signal injection

method which utilizes Kalman filtering is proposed to estimate

the rotor position at zero and low speeds. At high speed

applications, a direct scaling method which utilizes the machine

model is proposed. The two methods are combined by a

reasoning simple algorithm to estimate the rotor speed over the

entire speed range. The performance of the proposed estimation

method is tested via simulation using Maltlab and Simulink. The

results obtained showed the effectiveness and efficiency of the

proposed methods over a wide speed range with and without load.
