摘要
针对具有参数摄动广义线性系统的鲁棒状态反馈特征结构配置问题 ,提出了一种优化算法。该算法的设计目标是使闭环特征值和特征向量所满足的方程组关于参数摄动误差为最小。根据广义线性系统状态反馈特征结构配置结果 ,给出了优化指标的完全参数表示。该算法简单、有效 ,且可以给出鲁棒性较强的控制系统。
An optimization algorithm for robust state-feedback eigenstructure assignment in descriptor linear systems with parameter perturbations is given. The design criterion for the algorithm is to minimize the error in the set of equations which govern the closed-loop eigenvalues and eigenvectors. Based on the eigenstructure assignment result for descriptor linear systems, the parametric expression of the optimization index is obtained. The optimization algorithm is simple, effective, and produces control system with better robustness. A numerical example shows the effect of the proposed algorithm.
