摘要

为了抑制运载火箭自身结构参数变化和内外扰动对姿态控制精度和姿态稳定性的影响,设计了自抗扰控制器。通过跟踪微分器为期望姿态安排过渡过程,并提取其微分信号,然后利用扩张状态观测器,采用复合量测信息对系统的不确定项进行估计;设计姿态反馈控制器,利用扩张状态观测器估计的信号对不确定项进行实时补偿,实现对运载火箭的姿态控制。最后通过仿真说明了自抗扰控制器可以获得良好的动态性能、抗扰性和较强的鲁棒性。

Abstract

A novel active disturbance rejection controller( ADRC) of attitude was designed to attenuate effect of parameter variation and disturbances of launch vehicle on attitude control accuracy and stability. A tracking differentiator was proposed to arrange transient dynamics of desired attitude and provide differential signal of the attitude, then an extended state observer was designed to estimate and compensate impact of parametric uncertainties and disturbances by taking full advantage of information of gyros and attitude sensors. An attitude feedback controller was designed to realize attitude control by compensating the disturbances from the extended state observer. Simulation results show that ADRC exhibits better dynamic performance, higher ability and stronger robustness against external disturbance and parameter uncertainty.

Key words： launch vehicle; attitude control; active disturbance rejection control; extended state observer; robustness
