본 연구에서는 수동동작에서 표본화된 시간에서의 변위값들을 일련의 명령어로 변환하여 컴퓨터의 제어 신호로서 직류모터의 위치를 조작하여 동작시키는 것이다. 실제 실험에 있어서 기술상의 문제였던 가스의 정밀조정이 가능하였고 조작이 간편하여 사용상의 편리성을 얻을 수 있었다. 또한 자동 가스 조절용 직류모터의 실시간 모니터링 시스템을 연구, 개발함으로써 제품의 품질을 향상시킬 수 있었고, 전체 설비의 개발 또한 용이할 것으로 사료된다.

The accurate position control of pneumatic driving apparatus is considered in this paper. In pneumatically actuated positioning systems, accurate positioning as an electrical servo has been known to be difficult because of the friction force and compressibility of the air. For good control performance of the pneumatic system, an actuator mounted with externally pressurized air bearings is produced to compensate for friction force. For the controller design, the governing equation of the pneumatic driving apparatus is derived. In order to reduce the nonlinear characteristics of the control valve, linearized control input is derived from the relation between the effective area of the valve and the control input. The experimental results are presented to show the results of the improved position control of the pneumatic driving apparatus.

It is a quite quality concerning to control temperature of single crystalline growth as it does when you get most of heat treating products. It is also important factor to control temperature when you make the $Al_{2}O_3$(single crystalline) used to artificial jewels. glass of watches. heat resistant transparent glasses. Thus. it is a major interest to get the proper temperature in accordance with the time process while you are making mixture of oxygen and hydrogen to have the right temperature. In this paper. we will study of electrical valve positioning system for the gas mixture to improve the quality of products.

DC-Motor is needed more and more sophisticated control to follow the highest precision of industrial automation and used in a number of control equipment or industrial fields. It is also useful to control single crystal(Al2O3) growth. It is possible to procure a quality crystal utilizing a DC-Motor, if you mix Hydrogen and Oxygen gas properly and keep proper temperature in accordance with time process. In this paper, we will study about electrical valve positioning system for the gas mixture to improve the quality of single crystal($Al_{2}O_{3}$) growth and we will design about realtime monitoring systems of the automatic gas contol DC- Motor for single crystal($Al_{2}O_{3}$) growth
