分段预测函数控制及应用

Subsection Predictive Functional Control and Its Application

导弹在飞行过程中受到多种因素的影响,其传递函数在不断变化,常规控制方法很难满足控制要求.复杂的控制方法往往因计算量大,耗时较多而不能满足响应的快速性.预测函数控制法计算量小,且能适应系统参数一定程度的变化,但系统参数变化较大时,控制效果将下降.对导弹运行过程进行了研究,将飞行时间分段,每段以对应的特征参数作为预测模型的参数,采用预测函数控制的方法进行控制.研究结果表明,这种控制方法控制效果较好,且能满足快速性的要求,具有一定的实用价值.

The transfer function of missile changes continuously due to many factors in flight,which make it difficult for the conventional method to meet the control requirement.The complicated control method which needs much time can t meet the rapid response for the large amount of calculation.The predictive functional control method can adapt a certain degree of parameter change,and the amount of calculation is little.When the parameter change is smart,the control result will drop.The moving process of missile is ...
