中文摘要
临近空间高超声速飞行器在大空域飞行过程中, 呈现复杂的不稳定运动模态, 对控制器设计提出了较高的要求. 以一种通用临近空间高超声速飞行器纵向运动模型为研究对象, 在分析运动模态随飞行空域变化的基础上, 提出了一种基于轨迹线性化与反演控制相的轨迹跟踪控制方法. 该方法以参考轨迹为基准, 采用Jacobian线性化方法动态建立系统平衡状态, 采用反演控制方法对跟踪误差进行修正, 以实现对参考轨迹的精确跟踪, 并通过Lyapunov方法分析了系统的稳定性. 仿真结果表明, 论文所设计的控制器在高超声速飞行器大范围飞行过程中具有良好的跟踪性能.
英文摘要
The problem of control was put forward for the complicated unstable motion modal of the hypersonic flight vehicle in large space flight. Taking the longitudinal dynamics of a common Near space hypersonic flight vehicle as the target, a trajectory linearation and backstepping composed trajectory tracking control method was proposed based on the analysis of motion modal of the hypersonic flight vehicle in large space flight. The proposed control method constructed the equilibrium state based on the reference trajectory by the Jacobian linearation firstly, and then the backstepping control method with stability analysis based on the Lyapunov method was employed to correct the error, with which the accurate tacking realized. Simulation results show that the designed control method provided good tracking performance in the large space flight.
