Microcomputer Based Control of Frequency Regulator in Induction Motors
نویسنده
چکیده
The progress of semiconductor technology and control systems the last years has made possible the realisation of highly efficient and low priced microprocessor-based controllers for the control of asynchronous motors. This paper describes the design and realization of a microcomputer-based device for frequency regulation of an asynchronous motor. Through the regulation of motor’s supply frequency is achieved regulation of its speed. The control is based on PWM method, with voltage feedback, and frequency regulation is performed in the range of 20Hz to 60 Hz. The application platform is an automatic industrial press machine in a machines constructions company. Copyright © 2002 IFAC

Fuzzy Logic Based Life Estimation of PWM Driven Induction Motors
Pulse-width modulated (PWM) adjustable frequency drives (AFDs) are extensively used in industries for control of induction motors. It has led to significant advantages in terms of the performance, size, and efficiency but the output voltage waveform no longer remains sinusoidal. Hence, overshoots, high rate of rise, harmonics and transients are observed in the voltage wave. They increase voltag...

This paper presents an indirect adaptive system based on neuro-fuzzy approximators for the speed control of induction motors. The uncertainty including parametric variations, the external load disturbance and unmodeled dynamics is estimated and compensated by designing neuro-fuzzy systems. The contribution of this paper is presenting a stability analysis for neuro-fuzzy speed control of inducti...
متن کاملImproved Direct Torque Control for Induction Machine Drives Based on Fuzzy Sector Theory
Here, a new fuzzy direct torque control algorithm for induction motors is proposed. As in the classical direct torque control, the inverter gate control signals directly come from the optimum switching voltage vector look-up table, the best voltage space vector selection is a key factor to obtain minimum torque and flux ripples. In the proposed approach, the best voltage space vector is sel...
متن کاملAnalysis of the Frequency Effects on Design and Back-Iron Characteristics of Double-Layer Secondary Single-Sided Linear Induction Motors
Input frequency is one of the important variables in design and performance analysis of single-sided linear induction motors (SLIMs). Changing the frequency changes both the dimension of the SLIM in design process and the performance of the designed motor. The frequency influences the induced eddy currents in the secondary sheet as well as saturation level of the secondary back-iron. In this pa...
متن کاملA FUZZY-BASED SPEED CONTROLLER FOR IMPROVEMENT OF INDUCTION MOTOR'S DRIVE PERFORMANCE
Induction motors (IMs) are widely used in many industrial applications due to their robustness, low cost, simplicity and relative good efficiency. One of the major considerations for IMs is their speed control. PI (proportional-integrator) controllers are usually used as speed controller. Adjusting the gain of PI controller is time-consuming which needs thorough considerations. Hence, fuzzy con...
