SYSTEM FOR HIGH PERFORMANCE CONTROL OF INDUCTION MOTOR BY USING ADAPTIVE FNN CONTROLLER ACCORDING TO OPERATION CONDITION OF ELECTRIC MOTOR

摘要

PURPOSE: An adaptive FNN(fuzzy neural network) control system is provided to achieve improved efficiency and reduce energy consumption by controlling the speed of a motor in accordance with the operating condition. CONSTITUTION: An adaptive FNN control system comprises an adaptive FNN controller(6) for outputting command current of torque component required for speed control of an induction motor(9); a speed measuring unit(10) for measuring the speed of the induction motor input from the induction motor to the adaptive FNN controller; a vector controller(7) for receiving the command current of torque component, command current of magnetic flux component, and speed of induction motor, and outputting phase voltage command values; and a PWM inverter(8) for receiving the phase voltage command values, and driving the induction motor.
