During a long time, permanent magnet synchronous motor (PMSM) were only reserved for some specific applications, however, recently, these machines are becoming more used due to the powerful magnetic characteristic of the rare earth, being used in different areas. Several researchers have proposed implementations combining the use of permanent magnet synchronous motor with the direct torque cont...
Rare-earth magnets which are the best solutions for PMSM rotors are expensive which makes that other types of motors are used in the applications. The solution of the replacement of these motors with PMSynRM that use low-cost type of ferrite magnets becomes more tempting lately. This paper proposes two different types of low-cost ferrite solutions: first a V permanent magnet assisted synchronou...
Aiming at the characteristics of permanent magnet synchronous motor (PMSM) such as strong coupling and nonlinearity, we propose a fractional-order control scheme for the speed control of PMSM system based on the analysis of the fractional calculus theory. The simulation is conducted by using Matlab / Simulink. Simulation results indicate that the fractional-order PI controller can improve the d...
A method is presented for position control of a permanent magnet synchronous motor (PMSM). First a linear descretized state-space model of a PMSM with unknown parameters is identified; the identified model is then controlled using state feedback with integrator techniques. The simulation results of a typical motor are obtained and the influence of pole placement, noise and load variations is st...
The direct torque control theory has achieved great success in the control of permanent magnet synchronous motor. A Direct Torque Control (DTC) scheme of Permanent Magnet Synchronous Motor (PMSM) is presented. Based on in-depth analysis of PMSM mathematical model in abc frame and αβ frame are established and the operation principle of DTC-SVPWM system, the relationships between the torque and f...

Vector control has been widely used in control of permanent magnet synchronous motors (PMSM) where the information of rotor position is required. Shaft position sensor such as an optical shaft position encoder or Hall Effect sensor is fitted to provide a signal that is used to maintain an appropriate space angle between the stator and rotor fields in the motor. Even though this method is very p...
This paper presents the methods used in speed control of Permanent magnet synchronous motor (PMSM) drives. Permanent magnet synchronous motor(PMSM) are widely used in AC servo drives because of its high torque to inertia ratio, high power density, high efficiency and power factor as compare to the other motors used in drives. The study shows that the methods used to improve the performance of P...

This application note describes the design of a 3-phase Permanent Magnet Synchronous Motor (PMSM) vector control drive with 3-shunt current sensing with a position sensor. The design is targeted for automotive applications. This cost-effective solution benefits from a Freescale Semiconductor MPC5604P device dedicated for motor control. The system is designed to drive a 3-phase PM synchronous mo...
