This paper focusses on a discrete-time neural identifier applied to a Linear Induction Motor (LIM) model, whose model is assumed to be unknown. This neural identifier is robust in presence of external and internal uncertainties. The proposed scheme is based on a discrete-time recurrent high order neural network (RHONN) trained with a novel algorithm based on extended Kalman filter (EKF) and par...

In this paper, the model predictive control (MPC) technique has been used to control the speed of the linear induction motor (LIM) drive. The mathematical model of the LIM has been described in the stationary frame. The longitudinal end effects of the linear induction motor are taken into account as external load.The concept of field orientation is used to decouple the mover speed from the seco...

The sensorless model predictive force control (SMPFC) is a strong method for controlling the drives of three-phase 4(6)-switch inverter linear induction motors. This kind of inverter can be employed for fault tolerant control in order to solve the problem of open/short circuit in 6-switch inverters (B6). This paper proposed a method for the SMPFC of a linear induction motor (LIM) with a 4-switc...

Indirect field-oriented control (IFOC) of a linear induction motor (LIM) drive is an important challenge because the end effect and nonlinear behavior LIM drive. It becomes more complex in high-speed applications flux-weakening (FW) regions when current voltage constraints must be satisfied. Moreover, considering primary resistance constraint inequality makes calculations even complicated. This...

This work aims at the design of a roped elevator prototype, which uses a linear induction motor (LIM) as a traction machine. It is also concerned with the development of a specific inverter to feed the linear motor that allows several ways to drive the elevator through a suitable choice of the RMS voltage levels, angular phase displacement and electrical frequency of the output voltage. The res...

In this paper the position control of a linear induction motor using adaptive fuzzy backstepping design with integral action is proposed. First, the indirect field oriented control for LIM is derived. Then, an integral backstepping design for indirect field oriented control of LIM is proposed to compensate the uncertainties which occur in the control. Finally, the fuzzy integral-backstepping co...

This paper introduces a scaled PRT system, by which the expense and time for development can be reduced and the field applicability can also be improved. Furthermore, due to the propulsion based on the in-track linear induction motor (LIM), the need to carry motors and controllers on each vehicle and to provide guideway power rails can be eliminated, and thus the economical efficiency can be im...

First, the indirect field oriented control LIM is derived. Then, an integral backstepping design for indirect field oriented control of LIM is proposed to compensate the uncertainties which occur in the control. Finally, the adapt...

Linear induction motor (LIM) subway yard line often have very-small-radius curves and small turnouts with “S”-shaped in the middle. The lateral stability of train is low, wheel-climb (slipway) derailments occur at a speed 10 km/h. To study derailment safety limit linear running through line, coupling dynamic model train-track system established, fully considering driving characteristics motor, ...
