摘 要: 本文对参数未知的多变量系统,在不需要完全能控性的条件下,给出了间接多变量自适应极点配置控制系统稳定化的充要条件,成功地推广了陈翰馥的参数估计的非递推修正策略和递推修正策略,构造性地证明了该充要条件。文章的主要贡献是提出了多变量自适应极点配置系统稳定化的定义和充要条件,与以往算法相比,此算法进一步减少了系统所需的先验知识,仅需能观性指数。
关 键 词: 运筹学与控制论;自适应极点配置;能控性;参数修正策略;广义Sylvester矩阵

Abstract: The necessary and sufficient condition for stabilizing of multivariable adaptive pole-placement systems is given without controllability. Extending the methods of CHEN, the condition is constructively proved, by means of non-iterative and iterative modification strategies of estimated parameters. The main contributions include that the concept of stabilizing multivariable adaptive pole placement control and the related necessary and sufficient condition are presented. The possible singularity in the systems is completely avoided. The priori knowledge required by the strategy is only the observable indices, which is much less than the presented algorithms.
Key words: operation research and cybernetics; adaptive pole placement; controllability; parameter estimated modification strategy; extended Sylvester matrix
