Abstract
본 발명의 목적은, 유도전동기의 속도제어에 관해서, 저속운전시에 있어서의 속도센서 없이 벡터제어의 정도열화(精度劣化)의 문제 및 2차 저항변동에 의한 속도센서부 벡터제어의 정도열화의 문제를 해결하고, 지로속도 근방을 포함하여 고정도인 속도 및 제어를 가능케하는 벡터제어장치를 제공한다.An object of the present invention is to solve the problem of deterioration of vector control without speed sensor in low speed operation and accuracy of speed control part vector control due to secondary resistance variation in speed control of induction motor. The present invention provides a vector control device that solves the problem and enables high speed and control, including near the ground speed.
유도전동기를 구동하는 교류전원에 그 전원의 기본과는 틀리는 주파수의 교류신호를 중첩하고, 이 사이에 흐르는 전동기전류와 상기 교류신호의 전압, 혹은 발생하는 전동기전압과 상기 교류신호의 전류에 근거해서, 전동기의 철심에 있어서의 포화상태의 상위에 의해 발생하는 물리량(누설 인덕턴스)를 검출하고, 이 동작을 상기 기본파의 위상을 바꾸어서 복수회 행하고, 구하여진 복수의 물리량에 근거해서 전동기의 기본파자속의 위치(각)을 구하고, 이 자속위치 신호에 의해 유도전동기를 제어한다.An AC power source for driving an induction motor is superimposed on an AC signal having a frequency different from that of the power source, and based on the motor current and the voltage of the AC signal or the generated motor voltage and the current of the AC signal. And detect the physical quantity (leakage inductance) caused by the difference of the saturation state in the iron core of the motor, and perform this operation a plurality of times by changing the phase of the fundamental wave, and based on the obtained physical quantities, the fundamental wave of the motor The position (angle) of the core is obtained, and the induction motor is controlled by the magnetic flux position signal.
