基于标准系数法的飞控系统横侧向模态控制方法研究

基于标准特征多项式方法,对多输入系统进行了模态控制方法的研究.利用单输入模态控制的方法,将多输入模态控制的反馈矩阵等价为两个一阶矩阵的乘积形式,从而将多输入模态控制的问题转化为单输入模态控制的求解,选定特征参数值即可解出多维控制器矩阵,就可以将特征根配置在期望的位置,从而实现对飞控系统的控制.用该方法对某型飞机横侧向系统进行了设计,并分析了其鲁棒性和不同参数对飞机性能的影响.仿真结果表明,基于标准特征多项式的模态控制方法对飞机横侧向稳态保持系统进行设计是有效和简便的,系统有很好的鲁棒性,特征参数的选择也具有较大的范围,并且有很大的工程实践性.

Applying Standard Characteristic Polynomial Method to Designing Lateral-Directional Mode Control of Flight Control System

Sections 1 through 5 of the full paper explain fully the application mentioned in the title.Their core consists of:(1) we use the signal-input mode control method to equalize the feedback matrix of multi-input mode control with the product of two first-order matrixes;thus the multi-input mode control problem is converted into the signal-input mode control solution;(2) we solve the matrix of a multi-dimensional controller and configure the characteristic root to the desired position by selecting the value of...
