摘要
研究了有限对象集合同时镇定的基本理论问题。证明了4个对象可同时镇定的充要条件是存在4个稳定的多项式同时满足2个多项式方程。如果找到的多项式仅能满足其中一个方程,那么一定存在2个具有公分母或公分子的控制器使得它们分别同时镇定其中的2个对象。讨论了问题的可解性条件,进而给出了3个对象的分组与同时设计算法。
This paper studies theoretically some basic aspects of simultaneous stabilization of a finite set of plants. It is proved that four given plants are simultaneously stabilizable if and only if there exist four stable polynomials simultaneously satisfying two polynomial equations. If the obtained four polynomials satisfy only one of the polynomial equations, then there must exist two controllers having a common denominator or numerator such that each controller can simultaneously stabilize two of the four given plants. Further, the solvability of the polynomial equations is discussed and a design procedure of simultaneous stabilization of three plants is provided.
