针对高超声速飞行器的再入姿态控制问题,分别在全状态反馈和输出反馈的框架内,研究基于多变量干扰观测器-控制器综合的再入姿态控制策略,实现系统在不确定及外界干扰综合影响下对给定制导指令的高精度快速跟踪研究,并在Matlab/Simulink中进行仿真校验.通过仿真结果可以得出,基于输出反馈的干扰观测器-控制器对干扰有较好的响应,可以在遇到干扰时快速跟踪上期望值并保持稳定.
Aiming at the problem of reentry attitude control of hypersonic vehicle, the repositioning control strategy based on multivariate disturbance observer-controller synthesis is studied in the framework of full state feedback and output feedback, respectively. Under the influence of a given guidance for the instruction of high-precision fast track study, and in Matlab / Simulink simulation verification can be drawn through the simulation results, the output feedback-based disturbance observer - controller has a good response to interference, Can quickly track the expected value in the face of interference and remain stable.
