초록

본 논문에서는 ON/OFF 작동과 같이 단순화된 구동 메커니즘을 가지면서도 구동 명령 한계가 있는 시스템의 구동 위치 제어 기법 설계를 수행하였다. 가장 먼저 구동기 시험데이터를 이용하여 고려되는 구동기의 PWM 명령을 입력으로 하는 비선형/선형 구동 동역학 모델링을 수행 하였다. 선형화된 모델을 이용하여 목표로 하는 제어 성능 요구조건을 만족시키기 위한 고전적인 PI 제어기법을 설계하였으며, PWM 제어명령 한계에 따른 제어 성능 감소를 해소하기 위한 제어 알고리즘을 제안하여 유효 제어 범위 내에서 설계된 제어 성능이 구현되도록 하였다. 최종적으로 제어 시뮬레이션을 통해 설계 방법을 검증하고 해당 제어기법 적용에 따른 성능 개선 정도를 평가하였다.

In this paper, it is accomplished to design a control method for such an actuation system of simplified ON/OFF mechanism with actuation command limit. First of all, based on experimental data, the modeling works for nonlinear/linear actuation dynamics are performed, which are govern by PWM command as a control input. Using the linearized model, a classical PI control method is designed to satisfy the aimed control performance requirements, and a control algorithm is proposed to realize the required control performance in the effective control region through resolving the issue for the PWM command limit which reduces the control performance. Finally, through control simulations, the design method is verified and the corresponding control performance improvement is evaluated.
