Because of the low maintenance and robustness induction motors have many applications in the industries. Most of these applications need fast and smart speed control system. This paper introduces a smart speed control system for induction motor using fuzzy logic controller. Induction motor is modeled in synchronous reference frame in terms of dq form. The speed control of induction motor is the...

AC induction motor (ACIM) is the workhorse of industrial and residential motor applications due to its durability, robustness and reliability. In today’s energy conscious world, driving and controlling the induction motor efficiently are prime concerns. In the proposed scheme the v/f control of 3-phase induction motor uses the advanced VLSI technology that is a unique VLSI chip called Digital S...

This paper presents a generalized d-q model of nphase induction motor drive. Multi -phase (n-phase) induction motor (more than three phases) drives possess several advantages over conventional three-phase drives, such as reduced current/phase without increasing voltage/phase, lower torque pulsation, higher torque density, fault tolerance, stability, high efficiency and lower current ripple. Whe...

Electrical drives play an important role in rapidly growing industrial era, so the controlling of electrical drives is also important. Variable speed drives are the major part of power system, microelectronic, power plant and so on. Conventional controlling methods of electrical drives needed mathematical model of control process which was very tedious, that problem is solved by artificial inte...

Several field-oriented induction motor drive methods without rotational transducers have been proposed. These methods have a disadvantage that the rotor resistance variation causes an estimation error of the motor speed. Therefore, simultaneous estimation of the motor speed and the rotor resistance is required. This paper presents a method of estimating simultaneously the motor speed and the ro...

The aim of this paper is to present a new model for the linear induction motor (LIM), which is based on its equivalence with the asymmetrical rotary induction motor. The model uses the theory of positive, negative and zero sequence of symmetrical and asymmetrical components. Experimental and simulation procedures with a LIM prototype allowed the theoretical and experimental validation for this ...

The main purpose of this paper is to develop a high-level performance, and low-cost current sensorless control strategy for Induction Motor (IM) drives. Therefore, new phase-current regeneration method, vector in induction motor drives introduced. idea based on the reconfiguration Luenberger adaptive observer currents estimation, using information provided by dc-link voltage sensor. basis propo...

Induction Motor especially the squirrel cage type of this motor plays important role in industry. According to the application type, this motor place against various stresses that are caused failure in the motor. The most common failure is related to the Stator winding. Among these failures are turn-to-turn, coil-to-coil and phase to phase faults. Flow the high current do to the induction resul...
