针对高速飞行器控制方法中控制模型难以适应大包络飞行和算法中辨识存在收敛性的问题,设计了一种基于综合识别的在线控制方案。首先,由在线直接可测量构成三通道的特征状态量,以特征状态量建立面向控制的特征模型;然后,通过反馈线性化进行通道间的解耦,采用极点配置来进行在线控制参数的实时调节。仿真结果表明,在气动参数拉偏的情况下,三个通道均取得了较好的控制效果,控制器具有快速性和鲁棒性,且易于工程实现。
Aiming at the problem that the control model of high-speed aircraft control is difficult to adapt to the large-enveloping flight and the convergence of identification in the algorithm, an online control scheme based on synthetic identification is designed. Firstly, the characteristic quantity of the three channels which can form the three-channel can be directly measured by the on-line and the characteristic model of the control is established by the characteristic state quantity. Then, the decoupling between the channels is implemented by the feedback linearization, and the real-time adjustment of the online control parameters . The simulation results show that all the three channels have good control effect when the aerodynamic parameters are deviated and the controller is fast and robust and easy to implement.
