Abstract

The vibration, which often occurred in a two inertia motor system, makes it difficult to achieve a quick response of speed and disturbance rejection. This paper provides an autonomous pole assignment technique for three kinds of speed controllers (I-P, I-PD, and State feedback) using GAs(Genetic Algorithms) for a two-inertia motor system. Firstly, the optimal parameters are chosen using GAs in view of reducing overshoot and settling time, then those are used in computing the gains of each controller. Some simulation results verify the effectiveness of the proposed design. The proposed controller is expected to be the autonomous design way for controlling a two-inertia motor system with flexible shaft.

2관성 시스템을 제어할 때 자주 발생하는 진동은 빠른 속도 응답을 얻거나 외란 제거를 어렵게 한다. 본 논문은 2관성 모터시스템에 대해서 유전자 알고리즘을 사용하여 세 가지 속도 제어기(I-P, I-PD, 상태 피드백)의 자동 극배치 제어기를 설계하는 방법을 제시한다. 오버슈트와 세틀링 시간을 줄이는 관점에서 유전자 알고리즘을 사용하여 최적의 파라미터를 선정한 다음 이들을 각 제어기의 이득을 계산 할 때 사용한다. 몇 가지의 시뮬레이션을 통해서 제안한 제어기의 성능을 보인다. 제안한 제어기는 유연한 샤프트를 갖는 2관성 모터 시스템의 제어기의 자동 설계법이 될 수 있다.
