Abstract

PURPOSE:To obtain current control having high accuracy through which the effect of the induced voltage of the synchronous motor is eliminated by adding the detecting output of the induced voltage of the synchronous motor to current error signals conducting PID compensation control and inputting the detecting output to a power amplifier for driving the motor. CONSTITUTION:The output b of a positional detector 19 is inputted to a subtractor 1 together with rotor position command signals a, speed command signals c as the output are inputted to a subtractor 2 together with speed feedback signals d from a speed detector 18, and the output e is changed into current command signals f through a PID compensator 3 and inputted to multipliers 25- 27 while the signals d are inputted to multipliers 28-30. The signals b are also converted into a sine wave through a three-phase sine wave generating circuit 24 and inputted to the multipliers 25-30. Deviation between three-phase AC command signals h1-h3 from the multipliers 25-27 and detecting signals from current detectors 14-16 is taken by means of subtractors 5-7, and added to output m1-m3 from the multipliers 28-30 by means of adders 20-22 through PID compensators 8-10, and the output n1-n3 is inputted to the power amplifiers 11-13.
