Because the output signal of time grid sensor is so weak and easily affected by disturbing noise, it difficult to extract induction containing position information, when used detect rotor permanent magnet synchronous motor (PMSM). In this paper, an adaptive monostable stochastic resonance method proposed realize detection sensor. The tunnel magnetoresistance effect (TMR) adopted change magnetic...

This paper presents the application of the Linear Quadretic Gaussian (LQG) controller to the state estimation and feedback of a speed sensorless permanent magnet synchronous motor (PMSM) drive system. The nonlinear model of the motor has been linearized on the basis of field orientation principle. The standard Kalman filter technique has been used to estimate the speed, position, and load torqu...

The present paper will approach the design and analysis of a permanent magnet synchronous motor (PMSM) for automotive electromechanical braking (EMB) system. Due to technological and cost constraints, for the PMSM prototype a slightly different topology of the rotor is proposed. Finite element method will be used for analyzing the static performances of the former topology, and compare them wit...

In this paper, a new sensorless Interior Permanent Magnet Synchronous Motor (IPMSM) drives method with Extended Kalman Filter (EKF) for speed, rotor position and load torque estimation is proposed. The Direct Torque Control (DTC) technique for PMSM is receiving increasing attention due to the important advantages of the low dependence on motor parameters when compared with other motor control t...

Electric Vehicle (EV) is a dream for the human being city traffic without exhausting gas and with low noise. Permanent Magnet Synchronous Motor (PMSM) became at the top of ac motors in high performance drive systems such as EV. This paper presents a modern approach of speed control for PMSM using Particle Swarm Optimization (PSO) algorithm to optimize the parameters of PIController. The overall...

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...

K. D. Hoang, Y. Ren, Z.Q.Zhu*, M. Foster Abstract—The switching-table-based direct torque control strategies (ST-DTC) of dual-three phase permanent magnet synchronous machine (PMSM) drives are investigated in this paper. Owing to its inherited advantage of suppression of sixth harmonic torque pulsation, dual-three phase machine has attracted more and more interests among various sorts of multi-...

This paper proposes a digital hardware control of Permanent Magnet Synchronous Motor (PMSM) using a SiC MOSFET inverter implemented in a FPGA (Field Programmable Gate Array) device. High frequency is required using a SiC MOSFET inverter to obtain high response and good stability for speed control systems. Not only the switching frequency of inverter, but also the control frequency is achieved u...

With system parameters falling into a certain area, the permanent magnet synchronous motor (PMSM) is experiencing chaotic behavior which threatens the secure and stable operation of drive system. To control the undesirable chaos in PMSM, an adaptive dynamic surface control (DSC) law is first designed, which overcomes the problem of “explosion of terms” associated with the traditional backsteppi...
