摘要
提出了系统性设计最优控制的新方法。先是利用对称根轨迹确定加权阵Q和R的各种适当的组合,然后计算这些组合下系统的H_2范数。取H_2范数最小的设计。用这种方法设计的系统,其性能可以认为是用状态反馈所能达到的最好的性能。
A new systematic design procedure for optimal control is presented. At first the suitable combinations of the weighting matrices Q and R are selected by using the symmetric root locus. Then the H2 norms of the systems designed with these selected Q and R are computed and compared. The system with the least norm is considered as the final choice. The performance of such design can be regarded as the best obtained with state feedback.
