Fuzzy Control of Induction Motor
Using concepts of direct torque control, a fuzzy controller has been designed with a cascaded final state selector, which reduced rule base and gave birth to a new control technique of induction motor.In this text, an Application Specific Fuzzy Switching (ASFS) has been designed for direct torque control of squirrel cage induction motor, so space vector modulation for direct torque control shall be dealt subsequently. Control is generated by maintaining constant volts per hertz output; used to drive a pulse width modulated (PWM) circuit. Direct Torque Control with Space Vector Modulation: Direct torque control (DTC) combines fieldoriented control, digital signal processing and application specific integrated circuit.The mathematical model of induction motor observer estimates actual torque and flux of the motor from current and voltage feedback. If actual torque is below its differential hysteresis limit, the torque status goes high and if it is above its differential limit the torque status goes low. Induction Motor control technique with Fuzzy Logic The torque error, flux error and flux angle are given as the input parameters for the fuzzy controller. Defuzzification technique used here is mean of median and output denotes a switching state. Actual torque, flux and flux angle are determined from current and voltage feedbacks. Encoding Fuzzy Controller Output: The fuzzy controller selects optimal switching state,and then it is encoded for subsequent processing. The fuzzy controller is defuzzified to generate a crisp value, which is rounded off to the nearest integer value. Results: The fuzzy controller developed here alongwith the final state selector has been used to control an induction motor. Simulation model has been used to operate the motor at desired speed of 1500 r.p.m. In order to eliminate continuous maintained speed error, an integrator has been introduced after speed error is calculated. Accordingly, torque error and flux error are calculated and fed to fuzzy controller.

This article is presented by: Hassan Baghgar Bostan Abad Ali Yazdian Varjani Taheri Asghar Using Fuzzy Controller in Induction Motor Speed Control with Constant Flux ABSTRACT Variable speed drives are growing and varying. Drives expanse depend on progress in different part of science like power system, microelectronic, control methods, and so on. Artificial intelligent contains hard computation and soft computation. Artificial intelligent has found high application in most nonlinear systems same as motors drive. Because it has intelligence like human but there are no sentimental against human like angriness and.... Artificial intelligent is used for various points like approximation, control, and monitoring. Because artificial intelligent techniques can use as controller for any system without requirement to system mathematical model, it has been used in electrical drive control. With this manner, efficiency and reliability of drives increase and volume, weight and cost of them decrease. INTRODUCTION ECAUSE induction motors require low maintenance and are robust ,have many applications in industry . Along with industry progress, it indicates requirement to progresses drive with high performance. DC motors are control abler than AC motors but they require much cost. In addition, in equal power, DC motors have higher volume and weight. Main variations in semiconductors, converters topology, analyze technique and simulation of electrical machines drive and newer control technique have had role in this progress. Usually classical control is used in motors drive . Design and implementation of Conventional controls have difficulties that nameable: a) It is basis on mathematical accurate model of system that usual it is not known. b) Drives are nonlinear systems and Classical control performance with this system decrease . c) Variation of machine parameters (especially in vector control ) by load disturbance ,motor saturation or thermal variations do not cause expectation performance . d) Classical linear control shows high performance only for one unique act point. e) With choose improperly coefficient, classical control cannot receive acceptable result and suitable choose for constant coefficient in especial application condition with set point varying, necessarily is not optimum.
