The space vector modulation direct torque control system is introduced to the decoupling control system of bearingless permanent magnet synchronous motor (BPMSM) in this paper. The stator voltage and current are detected adopting Extended Kalman Filter(EKF) to estimate rotor's speed and position, therefore, the speed-sensorless operation of the control strategy is realized. The simulation results...
The demand for highly dynamic electrical drives, characterized by high quality torque control, in a wide variety of applications has grown tremendously during the past decades. Direct torque control (DTC) for permanent magnet synchronous motors (PMSM) can provide this accurate and fast torque control. When applying DTC the change of the stator flux linkage vector is controlled, based on torque and...
This paper presents the direct torque control (DTC) of a permanent magnets synchronous machine without mechanical speed and position sensors. Those are estimated by using the extended Kalman filter (EKF). The direct torque control (DTC) technique for PMSM is receiving increasing attention due to the important advantages the low dependence on motor parameters when compared with other motor control...
System with mechanical speed sensor has lower reliability and higher cost. Traditional direct torque control method has disadvantages of big ripples on current and flux linkage and torque. To solve these problems, the Extended Kalman Filter is established to estimate both stator flux linkage and rotor speed. Therefore, speed sensorless direct torque control for surface permanent magnet synchronous...
