摘　　要：根据循环冷却水供水系统非线性、大滞后、参数时变的特点,结合遗传算法和模糊控制以及传统PID控制各自的优势,设计了一种新型的控制器。仿真结果表明,这种控制器能根据被控对象不同工况变化的要求,获得满意的动态和静态控制特性,且抗干扰能力强。According to the characteristics of cooling water supply system, such as non-linearity, time delay and parameter time varying, taking advantages of genetic algorithm （GA）, fuzzy control and traditional PID control, a new controller was designed. The simulation results indicated that this kind of controller could follow different working situations of controlled objects to get satisfied effects of dynamic and stable control feature and had good anti-interference performance.
