摘　　要：预测控制是近年来发展起来的一类新型计算机控制算法。预测模型、滚动优化、反馈纠正适用于控制数学模型不易建立、且比较复杂的工业生产过程。针对球罐液位控制这一非线性系统 ,提出一种预测模型控制算法 ,使实际对象的动态响应品质获得有效的改善 。Prediction control is a kind of new computerized control algorithm developed in recent years. Prediction model, together with rolling optimization and feedback correction are well adapted for complicated industrial production processes of which control models are difficult to established. In accordance with non linear level control of spheroidal tank, a prediction model control algorithm is stated. The quality of dynamic response of practical object is enhance effectively, thus the control effect is excellent.
