灰色预测控制是以灰色系统理论为依据的一种全新的控制模式。该控制可实时地对被控对象建立具有外推预测功能的行为模型 ,并依此模型对系统的发展趋势进行预测 ,再根据盈亏率模型对系统实施决策与控制。该控制方式应用于跳汰机主要工艺参数自动控制系统后 ,简化了控制系统构成 ,提高了控制精度 ,稳定了跳汰机的工作状况 Gray prediction control is a brand new control mode based on gray system theory. The control can establish a behavior model with extrapolated prediction function for the controlled object in real time, predict the development trend of the system according to the model, and then make decision and control to the system according to the profit and loss rate model. After the control mode is applied to the automatic control system of the main process parameters of the jig, the control system is simplified, the control precision is improved, the working condition of the jig is stabilized
