| 中文摘要 | 主要研究非线性三轴稳定姿态控制器的设计,首先由航天器姿态运动的运动学方程和动力学方程建立其微分方程模型,以一组姿态误差微分方程表示的模态性能指标作为系统综合的目标,求解出一个包含干扰项的控制器。通过设计干扰观测器,得到一个非线性PID控制器。理论分析和仿真实验表明,各通道的跟踪性能和抗扰性能可以分别进行调节,而且被调参数意义直观,参数调节容易,适于工程应用。; Design of a novel nonlinear 3-axis stable attitude controller of spacecraft is studied.Firstly,a model of differential equations is deduced from dynamics and kinematics of spacecraft.Then a controller with a disturbance term is solved based on a modal performance index which is characterized by a group of differential equations about attitude errors.By designing disturbance observer,a nonlinear PID controller is derived.Theoretical analysis and simulation show that tracking performance and disturbance rejection can be adjusted respectively.And the regulated parameters are intuitive and easy to be adjusted,thus this controller is applicable in engineering. |
