控制系统误差估计及在反馈控制中的应用

THE METHOD OF CONTROLLER SYSTEM ERROR ESTIMATION AND ITS APPLICATION IN FEEDBACK CONTROLLER

利用最优不等距节点的样条函数表示制导工具系统误差 ,建立了一个能同时估计制导工具系统误差和外弹道测量系统误差的数学模型及参数估计方法 ,在此基础上 ,利用落点折合信息 。

In this paper, we use non isometric node spline function to express the system error of guidance instruments, the mathematical model for estimating both the system error of guidance instruments and that of orbit tracking is established, the estimator of this two kinds of errors is presented based on the theory of parameter estimation of nonlinear regression model, and a new method of feedback controller for missile accuracy is given by the bias information of the missile dropping point.
