Estimation of Steady- State Control Index of Complex Spacecrafts
Author(s): 
Pages: 1-9
Year: Issue:  1
Journal: AEROSPACE CONTROL

Keyword:  航天器控制精度稳定度;
Abstract: 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.
