Reentry attitude control based on adaptive multivariable disturbance compensation

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.

Research on control strategy based on multivariate disturbance observer-controller integrated reentry attitude in the framework of the full state feedback and output feedback respectively,which can track and research on high accuracy for custom guided instructions quickly under the comprehensive impact of uncertainty and external interference.Finally,perform simulation validation in Matlab/Simulink and analyze its stability.In the simulation we can see that,based on disturbance observer-output feedback controller has better response to interference,it can be encountered in the fast track the expectations and keep stable.
