摘　　要：针对船舶主机缸套冷却水温度控制系统的大惯性、纯滞后和时变性特点,提出了将等维新息灰色预测控制与模糊自调节PID控制相结合的新型控制策略,这种控制器可根据系统预测误差和变化率自动调整控制器参数,使控制器对系统响应具有适应性。仿真结果表明:灰色预测模糊PID控制比常规的PID控制与模糊PID控制有更多的优越性,自适应能力强,超调适中,具有更好的动、静态特性。Due to the large time constant, long time -delay and time -varying characteristic of marine diesel engine cylin- der cooling water temperature control system, a new fuzzy self - setting PID control strategy with grey prediction was presen- ted; it could automatically adjust controller parameters according to the predicted output error and error rate, which made the controller adaptive to the response of systems. Simulation results indicated that the strategy compared with traditional PID control and fuzzy PID control, had strong self - adaptive ability with better dynamic and static performance.
