PID 제어 시스템을 위한 전문가 관리 제어 = Expert Supervisory Control for PID Control System

다국어 초록 (Multilingual Abstract)

PID controller is being used in many servo control systems. However, when a control system has disturbance or time variable characteristic, it is very difficult to guarantee the robustness of the system. As a compensating way of solving this problem, in this paper, a expert supervisory control method for PID control system is presented. Expert supervisory controller is designed by error and error change, and nth control input is decided by the addition of (n-1)th control input and inference amount of increase or decrease. Control input of expert supervisory control is transmitted to input. The robust control function of expert supervisory control is demonstrated by the computer simulation.
