Sensitivity Measurement of Self-Tunig Controller to Modelling Errors (Power Spectrun Approach)

모델 오차에 대한 자기 동조 제어기의 민감도 측정

In the design of reference model based STC (self-tuning controllers), parameters of the controllers are determined not from the true plant but from the estimated model. In this paper, we suggest a power spectrum estimation method for visualling the sensitivity of the closed loop system without knowing the explicit original plant.
