【摘要】 将模糊预测和间歇ＰＩＤ控制器相结合，提出了变控制周期控制器．根据对被调量未来偏差和偏差变化率的模糊预测，合适地选择间歇ＰＩＤ控制器的控制周期，有利于改善具有大纯时滞对象控制系统的动态品质．最后由仿真结果说明了该方法的有效性更多还原

【Abstract】 This paper proposes a controller with variable controlling period which combines fuzzy forecast with intermittent PID controller. According to fuzzy forecast for future error and error rate of regulated object, we choose properly the control period of intermittent PID controller, which is beneficial to improve dynamic characteristic with long dead time process Simulation results demonstrate the effectiveness of the proposed method.更多还原
