| 摘要: |
| 针对滑翔式高超声速飞行器飞行环境复杂,临近空间再入段俯仰、偏航和滚转通道之间存在强耦合和参数大范围不确定性的特点,研究了飞行器双环结构协调解耦控制系统设计。首先建立了飞行器面向控制的动力学模型,对模型中的耦合项进行分析;然后将基于慢、快变量的双环控制与协调解耦控制相结合进行控制系统的设计,给出了解耦增益选取的一般方法;最后通过参数拉偏仿真及大包线全轨迹飞行仿真,对控制系统的性能进行了检验,验证了控制系统设计的有效性。 |

| Abstract: |
| Considering the complex flight dynamics characteristics, such as strong coupling and parameter uncer-tainty, we investigate a new control system design method combining double-loop control with coordinated decou-pling control for gliding hypersonic vehicles. Firstly, the dynamic model for the gliding hypersonic vehicle is estab-lished, and the strong coupling features are analyzed. Then, a double-loop coordinated decoupling control system for the gliding hypersonic vehicle is designed by combining double-loop control with coordinated decoupling control, and a generic decoupling gain selection scheme is presented. Finally, nonlinear simulation works of the control sys-tem on fixed point, parameter deviating and whole trajectory are carried out, and the simulation results and their a-nalysis show preliminarily that:(1) the designed control system can track attitude demands accurately;(2) the ef-fectiveness of the control system design method is verified. |
