  • In this study an one-board micom controlled precision temperature control system has been developed. The digital temperature control system is consisted of an one-board micom as digital controller, a 12-bit A/D and D/A converter, a power amplifier, a NTC thermister, a preamplfier and a heat chamber. An operating control program for the control system was written in Z80 machine language. A Dual-PID predictor control algorithm was proposed. Experments were conducted with different sampling time and limitted error value. As a result, the temperature in a heat chamber can be well controlled within +- 0.2 .deg.C when the sampling time was applied to 10 sec and the limitted error value +- 0.5 .deg.C under the dual-PID predictor control algorithm. By means of one-board micom overall system has been reduced in size and volume, thus the system becomes compact and less expensive.

  • 본 연구에서는 앞에서 개발된 온도 제어 시스템을 더욱 소형 경량화하기 위해 서 일반 마이크로 컴퓨터 대신에 원보드 마이컴(one-board micom)을 사용하였다. 원보드 마이컴은 프로그램을 기계어로 작성해야하는 어려움이 있으나 가격이 저렴하고 주변장치가 필요없으며, 크기가 작아 제어시스템을 소형경량화 시킬수 있는 장점이 있다.
