초록

본 논문은 2차 시스템에서 시간영역의 설계 사양을 만족하는 최적 강인 LQ-PID 제어기 설계방법을 제안한다. LQ-PID제어기 동조파라미터들은 시간영역의 설계사양인 오버슈트와 정착시간의 설계파라미터들과 LQR의 가중치요소 Q와 R의 관계에 의해서 설계될 수 있었다. 그래서 안정도-강인성뿐만 아니라 시간영역에서의 성능-강인성을 이룰 수 있었다.

This paper proposes an optimal robust LQ-PID controller design method for the second order systems to satisfy the design specifications in time domain. The tuning parameters of LQ-PID controller are determinated by the relationships between the design parameters of the overshoot and the settling time which are design specifications in time domain, and the weighting factors Q and R in LQR. we can achieve the performance-robustness in time domain as well as the stability-robustness.
