Implementation of the robust $H^{\infty}$ speed controller by auto-tuning of the weighting function

하중함수의 오토 튜닝에 의한 강인한 $H^{\infty}$ 속도제어기의 구현

In this paper, we are applied the Genetic Algorithm(GA) to design of the robust $H^{\infty}$ speed controller by auto-tuning of the weighting function. GA is used to design of the weighting functions in the robust $H^{\infty}$ controller. To evaluate the performances of the proposed robust $H^{\infty}$ controller, we make an experiment on $H^{\infty}$ speed controller of an actual DC servo- motor system with nonlinear characteristics. Experimental results show that proposed controller have better performance than those of PD controller.
