온도 안정화 전달함수 도출 및 이의 시뮬레이션에 의한 PID 계수 결정에 관한 연구

초록

In this paper, a new method for obtaining PID coefficients which are essential to a temperature stabilization process has been proposed. This method starts from measuring the open loop transfer function of the module, then the closed loop transfer function embodying PID control can be produced based on this. Finally, the simulations using a few PID coefficients and the performance analysis for those results provide the best PID coefficients which are effective in a fast setting to a target temperature, a less current needed, and less deviation from steady state. The measurement using the derived PID coefficients, showed , %OS = 16, and stabilization within ±0.02[oC] for several hours. In addition to light sources like SOA, the proposed method can be utilized for any device needs temperature stabilization.
