In this study, an improved sliding mode control (ISMC) method combining continuous non-singular terminal (CNTSM) and linear active disturbance rejection (LADRC) for permanent magnet synchronous motor (PMSM) servo system is proposed to improve the performance of PMSM. Based on mathematical model PMSM, combined with SMC theory LADRC theory, CNTSM controller based function solve singularity (TSM) ...

Rapid developments are occurring in design of electrical machines and its control. To get optimum performance under normal/fault condition needs implementation of fault tolerance. Next decade is of Permanent Magnet Synchronous Machines. The paper presents mathematical modeling of PMSM. A current and speed controller is designed to implement fault tolerance and its stability analysis.

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...

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...

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...

Abstract: In order to solve chattering problem of conventional sliding mode observer (SMO), this paper proposes a exponential reaching law sliding mode observer (ERL-SMO) for a permanent magnet synchronous motor (PMSM) which substitutes exponential reaching law for constant reaching law. The ERL-SMO estimates the rotor position and the angular velocity from the back electromotive force (EMF) ba...

Estimation of parameters Permanent Magnet Synchronous Motor (PMSM) plays an important role for motor controller tuning in Electric Vehicle (EV) application. Under running condition vary due to different effects such as temperature, saturation and Voltage Source Inverter (VSI) non-linearities. Identification increases the control performance system. This paper uses Extended Kalman Filter (EKF), ...

Among all types of electrical motors, permanent magnet synchronous motors (PMSMs) are reliable and efficient motors in industrial applications. Because of their superiority over other kinds of motors, they are replacing conventional electric motors. On the other hand, high-phase PMSMs are good candidates to be used in certain industrial and military projects such as electric vehicles, spacecraf...
