This paper considers a class of networked Permanent Magnet Synchronous Motors PMSMs , whose feedback loops are closed over a shared data network. Although the installation and maintenance cost of the networked PMSM system can be lowered by replacing the conventional point-to-point feedback cables with a network, the network packet dropouts and transmission delay may degrade the system’s perform...

Permanent magnet synchronous motor(PMSM) is a exceedingly efficient motor and is successfully operated in a wide range of speed. Various types of permanent magnet synchronous motors are accessible in the market offering advantages of direct on line starting as induction motor and effectively running on synchronous speed. Major disadvantages of PMSM is uncertainty of successfully synchronization...

In this paper, the torque production of fractional slot concentrated winding (FSCW) permanent magnet synchronous machines (PMSM) are analyzed from the perspective of the air-gap field harmonics modulation accounting for slotting effect. It is found that the average torque of FSCW PMSM is produced by both the principle of conventional PMSM and the magnetic gearing effect. A finite element analys...

Dc excitation of the field winding in a synchronous machine can be provided by permanent magnets. Permanent magnet synchronous machine (PMSM) can offer simpler construction, lower weight and size for the same performance, with reduced losses and higher efficiency. Thanks to the mentioned advantages these motors are widely used in different application, therefore analysis and modeling of the...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract In the last 20 years Permanent Magnet Synchronous Machine (PMSM) are becoming more indispensable in many industrial applications. The PMSM is superior to both induction motor drives and DC motor drives because of the inherent advantages of these mo...

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...

Permanent magnet synchronous motors (PMSM), so that the production of high power density and high torque for industrial applications, more and side with a wide range of applications. In this study was presented in the MATLAB / SIMULINK simulation environment of Permanent Magnet Synchronous Motor. PMSM has been driven with insulated gate bipolar transistors (IGBT) inverter as producing Pulse Wid...

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...

For reducing the steady state speed ripple, especially in high performance speed servo system applications, the steady state precision is more and more important for real servo systems. This paper investigates the steady state speed ripple periodic disturbance problem for a permanent magnet synchronous motor (PMSM) servo system; a fuzzy adaptive repetitive controller is designed in the speed lo...
