| 摘 要： | 未来复杂航天器应该按照期望的指向精度和稳定度来设计恰当的姿态控制系统。本文在全面考虑测量噪声、对象不确定性、环境扰动、执行机构与控制器非线性的前提下 ,首先分析了控制参数对稳态控制品质的影响 ;然后在详细探讨了测量噪声传播效应的基础上 ,提出稳态控制精度和稳定度的估计方法 ;最后通过对不同的噪声、不确定性、摄动和非线性情形进行大量仿真验证 ,结果同估计分析完全吻合

| Abstract: | For future complex spacecrafts, appropriate attitude control system should be designed according to desired accuracy and stability. In this paper, firstly the effect of control parameters on steady-state performance is analyzed, taking into consideration of the actual control systems with such complicated cases as measurement noises, uncertainties, environment disturbances and nonlinearities of actuator and controller. Secondly, based on discussion of the propagation of measurement noises, an estimation method of control accuracy and stability is proposed. Finally, plentiful simulation is taken for different noises, uncertainties, disturbances and nonlinearities, and the results are agreed with the estimation completely. |
