Many control schemes have been proposed for induction motor and permanent magnet synchronous motor control, which are almost highly complex and non-linear. Also, a simple and efficient method for unified control of the electric moto are rarely investigated. In this paper, a novel control method based on rotor flux orientation is proposed. The novelties of proposed method are elimination of q-ax...

In this paper, a method of calculating the parameters of equivalent circuit model of linear induction motor(LIM) is proposed based on numerical analysis and finite element method(FEM). The method is proved accurately through the traditional removed and locked tests. Material change of reaction plate’s effect on how equivalent circuit’s parameters change and the influence on thrust and vertical ...

To implement an automatic picking system (APS) in distribution center with high precision and high dynamics, this paper presents a design of a linear induction motor (LIM) drive and robust position controller based on an integral sliding mode control (SMC) scheme. The force disturbance as well as the mechanical parameter variation such as the mass and friction coefficient influences directly on...

Vector control schemes have recently been used to drive linear induction motors (LIM) in high-performance applications. This trend promotes the development of precise and efficient for individual motors. research aims present a novel framework speed thrust force LIM using space vector pulse width modulation (SVPWM) inverters.

In this paper, discrete-time inverse optimal control for trajectory tracking is applied for a three-phase linear induction motor (LIM). The system mathematical model is in the Nonlinear Block Controller Form (NBCF) in order to achieve trajectory tracking. The control law computes the input voltage signals which are optimal in the sense that this control law minimizes a meaningful cost functiona...

This paper deals with the present scenario of magnetic levitation with LIM. The magnetically levitated train has no wheels, but floats-or surfs-on an electromagnetic wave, enabling rides at 330 miles per hour. By employing no wheels, maglev eliminates the friction, and concomitant heat, associated with conventional wheel-on-rail train configurations. There are two basic types of non-contact Mag...
