| 摘 要： | 主要研究了区间对象族的鲁棒镇定问题。区间对象族满足可镇定性条件，即每一个对象都没有不稳定的零极相消，是其鲁棒镇定问题可解的一个必要条件。本文将说明区间对象族满足可镇定性条件同时也是其鲁棒镇定问题可解的充分条件，并通过示例说明区间对象族最优鲁棒控制器的设诗过程。

| Abstract: | The robust stabilization problem (RSP) for interval plant family was studied. A necessary solvability condition of RSP is that every member plant must be stabilizable, that is, it is free of unsta?ble pole-zero cancellation. It is shown that stabilizability is also a sufficient solvability condition of RSP. The numerical example was presented to illustrate the procedure of the synthesis of the optimal robust controller for the interval plant family. |
