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...

The paper presents a space-vector pulse width modulation (SVPWM) inverter feeding a permanent-magnet synchronous motor (PMSM). The SVPWM inverter enables to feed the motor with a higher voltage with low harmonic distortions than the conventional sinusoidal PWM inverter. The control strategy of the inverter is the voltage / frequency control method, which is based on the space-vector modulation ...

Fractional calculus is a generalization of the integration and differentiation to the fractional (non-integer) order. In this paper, for the first time, we devised a fractionalorder adaptive compensation (FO-AC) method for cogging effect minimization for permanent magnetic synchronous motors (PMSM) position and velocity servo system. Cogging effect is a major disadvantage of PMSM. In our FO-AC ...

This paper presents an interesting hybrid solution to a challenging estimation and control problem of the Permanent Magnet Synchronous Motor (PMSM). Apart from inherently nonlinear nature PMSM, which makes this particularly challenging, is unavailability measurements, rotor position, speed.

Abstract In the permanent magnet synchronous motor (PMSM) control system, phase current sampling unit is an important part of whole system. Traditionally, hall-effect components are used to detecting currents PMSM. However, size hardware with Hall-effect often large. this paper, a scheme PMSM by using three resistors on main circuit was discussed. order overcome phenomenon that flow discontinuo...

performing fast and accurate methods for modeling the electrical machines has been the subject of several studies and many authors proposed different procedures to attain this aim. beside the accuracy, the speed of the method is of great concern. on the other hand, the capability of the method to be changed according to the need is another important issue. finite element method provides relativ...

This paper presentsan investigation of a 3D-magnetic flux permanent magnet synchronous motor (3D-MF PMSM) used for electric vehicle applications. The investigated 3D-MF PMSM consists an integrated radial-flux and axial-flux structure. It has two air-gaps air-gaps, as well toroidal winding wound stator. structure helps to concentrate all the within maximize torque production. Moreover, there are...

Abstract This study investigates the chaos control in permanent magnet synchronous motor (PMSM) using a Lyapunov‐based model predictive approach subject to data loss. PMSM, as rich nonlinear dynamic, can demonstrate chaotic behavior when its parameters are certain area. Thus, performance of system will degrade this condition. Moreover, some networked applications, especially modern automation i...

This paper presents the design of a Neural Network based approach to improve efficiency in a vector control of Permanent Magnet synchronous Motors (PMSM). The conventional Proportional-Integral (PI) controller is largely used in industry because of the robustness this regulator procures. But in some case, when the dynamics of the system vary over time or with operating conditions, the performan...
