针对实际控制对象内部特性不能确定的情况,给出了基于离散辨识模型的模态控制方法。研究了以离散标准二项式作为系统标准特征方程的完全状态向量信息线性离散对象的模态控制方法,提出了基于离散辨识模型的线性对象模态控制系统建立的算法,分析了系统标准特征方程的根参数对控制系统过渡过程性能的影响。这种方法具有建立简便,工程可实现性强等特点。

A modal control method based on discrete identification model was proposed in order to resolve interior uncertainty of actual control plant. The modal control method for linear discrete plant of complete state vector information was studied by using discrete standard binominal as system standard eigenequation. A methodology constructing modal control system of linear plant based on discrete identification model was proposed. Analysis results which eigenroot parameters influenced on system performance were given. The method characters are that it is easy to constructing and engineering implementing.
