Abstract

In this paper, the system to control the PWM inverter-induction motor drive system including ac current sensors, voltage sensors, and an encoder through the network is developed. Although the network-based control for an induction motor drive system is becoming increasingly important at factory automations, there will inevitably be time delay from the sensors to the motor control system, which may cause the instability. The algorithm to minimize the efforts for network induced time delay of sensor data is proposed, using both the synchronous signal and the method for estimating sensor data. The experiments with DSP are carried out in order to verify proposed algorithms.

본 논문은 교류전류 센서, 전압센서 및 엔코더를 포함한 PWM인버터-유도전동기 구동장치 전체를 네트워크로 제어하는 시스템을 구현한다. 네트워크 기반 유도전동기제어는 공장자동화에 중요한 이슈로 되고 있으나, 센서와 제어기 사이에 센서데이터의 통신기연에 의해 전동기 구동시스템의 안정성을 저하시키는 문제가 있다. 따라서 동기신호 및 센서데이터의 예측기법을 사용하여 네트워크에 의한 센서데이터의 시간지연을 최소화시키는 기법을 제시한다. DSP를 사용한 실험을 통하여 제시한 기법의 타당성을 확인한다.
