SPEED CONTROL APPARATUS OF A MOTOR FOR A HORSE RIDING MACHINE

摘要

PURPOSE: The speed controlling apparatus of a motor in a horse riding machine is provided to uniformly control the speed of the motor regardless of regions using a vector control algorithm. CONSTITUTION: A speed controller(10) compares instructed speed and estimated speed and generates/outputs an instruction current. A current controller(20) compares the instruction current and a detected current and generates/outputs an instruction voltage. A coordinate converter(30) generates/outputs a d-q coordinate current and an orthogonal coordinate voltage. A pulse-width modulation generator(40) outputs the control voltage of the motor based on the orthogonal coordinate voltage. A main controller(80) detects the location and the speed of a motor rotor.
