摘　　要：将灰色预测理论与常规PID控制结合,对灰色预测PID控制在稳压器压力控制系统中的应用进行了研究,在传统压力控制系统的反馈回路中添加了灰色预测控制器,该控制器以灰色GM(1,1)模型为基础,用被控量的灰色预测值替代当前测量值进行超前控制;仿真分析结果表明:基于灰色预测控制算法设计的稳压器压力控制系统性能优于常规PID控制;系统的控制品质得到了改善。Combining the grey prediction theory with conventional PID control, the grey prediction PID control technology in the control of pressurizer pressure control system was analyzed. The grey prediction controller based on grey GM （ 1, 1 ） model was added in the feedback loop of pressure control system. The advanced control can be conducted by using the grey prediction values instead of current measured values. The simulation results show that the pressurizer pressure control system based on grey prediction algorithm is superior to conventional PID control system. The control system is improved by grey prediction.
