A new scheme to design the proportional integral (PI) type controller for speed control of a constant Volts/Hz (V/F) three phase induction motor drive employing a matrix converter has been presented. An approximate linear model of induction motor operating in constant Volts/Hz scheme is derived and a design example of a slip controller for a three phase motor is presented. Performance of the de...

In this paper, the Linear Exponential Quadratic Gaussian with Loop Transfer Recovery (LEQG/LTR) methodology is employed for the design of high performance induction motor servo systems. In addition, we design a speed sensorless induction motor vector controlled driver with both the extended Kalman filter and the LEQG/LTR algorithm. The experimental realization of an induction servo system is gi...

This work presents, demonstrates and analyzes a property that relates the transient response of stator and rotor currents to the speed of induction motors and their parameters. The straightforward application of this property allows determining the rotation speed of the motor and detecting a failure or variation of its parameters. This property is demonstrated analyzing the induction motor mode...

Speed Induction Motor (IM) control is an area of research that has been in evidence for some time now. In this paper, a nonlinear controller presented the induction motor drives. The designed based on input-output feedback linearization technique. decouples flux from speed and makes synthesis linear controllers possible. This article associated with NPC three level inverter defective, faults ar...

This paper deals with the synthesis of fuzzy state feedback controller of induction motor with optimal performance. First, the Takagi-Sugeno (T-S) fuzzy model is employed to approximate a non linear system in the synchronous d-q frame rotating with electromagnetic field-oriented. Next, a fuzzy controller is designed to stabilise the induction motor and guaranteed a minimum disturbance attenuati...

Induction motor is a typical member of a multi-domain, non-linear, high order dynamic system. For speed control a three phase induction motor is modelled as a d–q model where linearity is assumed and non-idealities are ignored. Approximation of the physical characteristic gives a simulated behaviour away from the natural behaviour. This paper proposes a bond graph model of an induction motor th...

This paper proposes a modified dynamic equivalent circuit model for linear induction motor considering both longitudinal end effect and transverse edge effect. The (speed-dependent effect) is based on conventional Duncan’s approach. investigated by using three correction factors applied to the secondary resistance magnetizing inductance. Moreover, iron saturation effect, skin air-gap leakage ar...
