一种连续系统辨识方法及其在飞控规律辨识中的应用

针对某型飞机控制系统的规律辨识问题，对文献2,3]提出的连续系统辨识方法进行了改进，给出了该方法可以适用的辨识对象的一般模型，同时通过对误差模型和极小化指标的改进，把原方法推广至时变参数辨识领域。数值仿真结果表明该方法成功的解决了该飞控系统的辨识问题。该方法还很容易推广到一类具有相同特征的线性，非线性，时变或时不变的参数辨识中。

A Continuous System Identification Approach and Its Application in Flight Control Laws

To aim at the identification of a certain type of flight control laws,an improvement is made on the method of continuous-time identification that is presented on the articles.A general model of the identification target is given,which is suitable for this kind of method.And also,by improving the guideline of error model and minimum criterion,the original approach is extended to time-variable area. Numeric simulation results show that this method successfully solves the identification problems of flight control system.And,the method can be easily spread to some parameter identification that is linear,nonlinear,time-variable,or noontime-variable.
