Abstract
마이크로 프로세서를 이용한 디지탈 공정제어 수단이 고찰되었다. 관심의 초점은 분산-종합제어에 적합한 단말제어 프로세서에 두었다. 시험 제작된 프로세서는 8개의 제어 루우프를 운전하는 독립된 제어장치이며 동시에 종합제어를 위하여 상위 전산기와 데이타 교환이 가능하도록 설계 되었다.

주기적 샘플링에 의한 비례-적분-미분(PID)제어방식을 기본으로 하고 있으며 파라메터 값에 의하여 PI,PD등으로 축소될 수 있도록 하였다. 시험 장치에서는 주기를 2초로 하였는데 A/D변환기의 적절한 선정에 의하여 0.2초정도 까지는 쉽게 단축할 수 있다. 조작자용의 프로세서에 대한 고찰은 최소한의 기능을 가진 것에 한정하였으며 이는 실제 적용 현장과 관련하여 기능이 확장되어야 할 것이다.

사용된 마이크로 프로세서는 범용의 것으로 단말용에는 M6800계통을, 조작자용에는 SC/MP계통을 사용하였다.
A microprocessor based digital process controller has been studied. The objective was to develope a stand-alone terminal processor for distributed on-line control systems.

The prototype terminal proposed in this paper has the capability of handling eight independent control loops under the supervisory control of main computer and/or operator console.

The control algorithm follows analog PID action based on periodically sampled data. The control action can also be reduced to PI,PD and so forth through parameter assignment. Availability of A/D converters to the authors limited sampling period to 2 seconds, but it could easily be reduced to 0.2 sec. employing appropriate A/D devices.

The number of operational functions of console processor is kept minimum in this study, the expansion of which should be done for particular application. Hardware implementation was done with general purpose microprocessors; M6800 system for terminal and SC/MP system for console.
