摘　　要：线性系统的结构分解 ,揭示了状态空间的本质特征 ,为最小实现问题的提出提供了理论依据 ;实践上 ,有力地促进着系统状态反馈、系统镇定问题的解决 .为了能直观、充分地理解系统结构的本质 。Structural decomposition of line ar system not only expresses the essence of the state space but also puts forwar d the theoretical basis to the minimal realization.As a result,it improves the solvement of state space feedback and stabilization of linear system.System s tate space decomposition's mechanism and controlled decomposit ion of low dimension system and the vivid presentation are studied so as to know the system structure essence.
