摘　　要：本文考虑时变动力学系统在比例微分反馈律下的特征结构配置问题,给出了问题的充要条件;建立了问题的解集合关于两组参向量和闭环特征值的参量表示。所得结果没有对闭环极点附加任何限制条件,最广泛地概括了反馈动力学系统的闭环结构性质。基于这一结果,本文还简要地讨论了(时变)动力学系统控制中的一些问题。In this paper, the eigenstructure assignment problem for time-varying dynamical systems by using proportional and differential feedback is considered, suffident and necessary condition for the problem is given, parametric representation of the solution set to the problem with respect to the dosed loop poles and two series of parameter vectors is established. The obtained eigenstructure assignment result does not impose any restriction on the closed loop poles, and deeply reveals the structural property of linear feedback dynamical system. Based on this result, problems related to the control of (time-varying) dynamical systems are simply discussed.
