摘要
考虑了具有摄动的广义二阶动力学系统的鲁棒特征结构配置问题,提出了一种优化算法.该算法的目标是使得特征结构配置的误差最小.根据广义二阶动力学系统基于状态加微分反馈的参数化特征结构配置结果,给出了优化指标的完全参数形式.该算法不包含"返回"过程,允许特征值在一定范围内参与优化,能够给出鲁棒性较强的控制系统.数值例子说明了算法的有效性.
Robust eigenstructure assignment in descriptor second-order systems is considered; and an optimization algorithm is given for minimizing the error of the eigenstructure assignment. Based on the parametric eigenstructure assignment result for descriptor second-order systems, the parametric expression of the optimization index is obtained. The optimization algorithm does not contain "going back" procedures, and allows the closed-loop eigenvalues to be optimized within desired regions. A numerical example demonstrates its validity.
