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...

This paper proposes a novel extended electromotive force (EEMF) observer of dual three-phase permanent magnet synchronous motor (DTP-PMSM) operable to the position sensorless overmodulation drive. The drive occurs in current harmonics, and estimated EEMF also contains harmonic components, leading ripple error position. Based on vector space decomposition (VSD) utilized DTP-PMSM control, propose...

-Permanent Magnet Synchronous Motor (PMSM) is widely used in high–performance drives such as industrial robots and machine tools. It characteristics of high efficiency, simple structure, higher torque /inertia ratio, maintenance free and easy to control. The higher torque density and high efficiency make PMSM as a better option as compared to induction motor. The torque in PMSM is usually contr...

Abstract This paper discussed the performance changes under a rated operation state and permanent magnet loss-of-field fault of 5KW synchronous motor (PMSM) in 200 mm shaftless rimless thruster. These key parameters include air gap flux density, back electromotive force, output torque, current magnetic field. Using these to analyze running provides reference for early diagnosis at simulation le...

This paper presents a neural network controller for permanent magnet synchronous motor (PMSM). The neural controller is used for torque ripple minimization of this type of motors. Two methods of neural controller design are used. The first method is based on two loop controllers (current controller and speed controller). The second method is based on estimation of torque constant and stator res...

This paper discusses two observers, which are used for the estimation of parameters of PMSM. Former one, reduced order observer, which is used to estimate the inaccessible parameters of PMSM. Later one, full order observer, which is used to estimate all the parameters of PMSM even though some of the parameters are directly available for measurement, so as to meet with the insensitivity to the p...

A novel digital implementation of speed controller for a Permanent Magnet Synchronous Motor (PMSM) with disturbance rejection using conventional observer combined with Extended Kalman Filter (EKF) is proposed. First, the EKF is constructed to achieve a precise estimation of the speed and current from the noisy measurement. Second, a proportional integral derivative (PID) controller is developed...

Abstract: This paper deals with the design of sliding mode control and neural network compensation for a sensorless permanent magnet synchronous motor (PMSM) controlled system that is able to improve both power consumption and speed response performance. The position sensor of PMSM is unreliable in harsh environments. Therefore, the sensorless control technique is widely proposed in industry. A...

Considering inevitable asymmetry of parameters in motor, pulse cancellation theory is proposed which releases duty cycle freedom conventional zero CM voltage (ZCMV) w...

In this paper, the driver with antiwindup and fuzzy high-performance and robust PI controller has been suggested for Permanent Magnet Synchronous Motor (PMSM).
