RCGA기법을 이용한 선박용 디젤 주기관의 속도제어

Speed Control of Marine Diesel Engine using RCGA

The conventional PID controller has been extensively used to an industrial world though modem control theory has been developed in these days. Because control action of PID controller depends on three parameters engineers easily understand how to deal with control parameters. As a result many kinds of tuning methods of PID controller such as Ziegler-Nichols method, Cohen-Coon method, Pole-Zero placement method, IMC method etc. But these methods need the experience on the controlled system. Genetic Algorithm which is a sort of optimization methods can search the control parameters for the selected plant via systematic procedure. In this paper, the author present searched PID control parameters using a GA for a marine diesel engine and prove the excellence of GA through a simulation.
