摘要
高超声速飞行器的强耦合性、模型阶数高、气动参数摄动的特点,使得一般控制器很难达到理想的控制效果。自抗扰串联技术能够很好的满足高阶模型控制的要求。自抗扰主要特点就是可以在有限的条件下观测到系统的干扰总和并加以补偿。同时利用滑模变结构技术对参数摄动的不敏感性,加强系统抗扰能力。仿真结果显示控制效果很好。
The strong coupling of the hypersonic vehicle, the high order of the model, and the perturbation of the aerodynamic parameters make it difficult for the general controller to achieve the desired control effect. The self-disturbing tandem technique can well meet the requirements of the high-order model control. The use of sliding mode variable structure technology which is not sensitive to perturbation of parameters can enhance the system immunity. The simulation results show that the control effect is very good.
