This paper deals with the design and evaluation of a robust controller for static VAR compensator (SVC) in remote industrial power systems to enhance the voltage profile for three-phase single cage induction motor (SCIM) loads. The controller design is based on H∞ theory to deal with uncertainties arising in industrial network modelling. The performance of the H∞ controller has been evaluated...

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...

The linear Induction motor, first conceived in the 19 century, could present a viable solution to the problem of quick and efficient transportation. However the performance of Single Sided Linear Induction Motor (SLIM) is severely degraded by ‘end effects’ and ‘transverse edge effects’. The present work is an attempt to investigate the magnetic flux distribution within the air gap and other reg...

In this paper, a new approach is proposed for the optimum design of single-phase induction motor. By using the classical design equations and the evolutionary algorithms such as Genetic Algorithms (GA), Particle Swarm Optimization (PSO) and Modified Particle Swarm Optimization (MPSO), a Single Phase Induction Motor (SPIM) was designed with the maximum efficiency. The Finite Element Method (FEM)...

A comparative study of the various methods for design of an induction motor is presented. This deals solutions of a large number of non-linear equations and consequently some modifications of the methods have been suggested for use in practice. Modifications of the gradient theory, dynamic programming and statistical search is also made for optimal design. Besides, dual criteria optimization pr...

the use of micro-controllers in actuators provides extended flexibility for on-line data acquisition and sophisticated control implementation. however, attempts to utilize the excellent features of induction motor that is deemed by its strength, robustness, high torque, and relatively low cost in actuators face a fundamental control design challenge. the purpose of this paper is to introduce th...

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...

Recently, single linear induction motor(SLIM), which comes from rotary induction motor(RIM), has been widely applied in transportation systems, especially in intermediate speed arrange, because of its merits, such as ability to exert thrust on the secondary without mechanical contacts, high acceleration or deceleration, less wear of the wheels, smaller turn circle radius and more flexible road ...

An adaptive backstepping sliding mode controller. wluch combincs both the merits of adaptive backstepping control and sliding mode control, is proposed to control the mover position of a linear induction motor (LIM) drive to compensate for the uncertainties including the friction force. First, the dynamic model of an indirect field-oriented LIM drive is derived. Then, a backstepping sliding mod...

The area of multiphase variable-speed motor drives in general and multiphase induction Motor drives in particular have experienced a substantial growth since the beginning of this century. Research has been conducted worldwide and numerous interesting developments have been reported in the literature. An attempt is made to provide a detailed overview of the current state-ofthe-art in this area....
