This paper deals with optimum PI controller design using genetic algorithm to improve control performance and robustness for an oil cooler system. The gain was found minimize object function, integrated absolute error, satisfy specifications such as overshoot settling time based on practical transfer function of the were investigated by comparing indicial responses Bode diagram analysis respect three kinds gains obtained from different decision manners. Moreover, against input disturbances, sinusoidal wave form abrupt single pulse, evaluated. computer simulation results showed that suggested can establish desirable strong easy process.
