| 中文摘要 |
| 本文将线性最优控制理论、灵敏度分析及线性规划有机地结合起来，圆满地解决了线性最优控制设计中权矩阵的优化选取问题。同时还指出，权矩阵的优化选取，不仅能够改善控制系统的动态品质，而且可以简化控制系统的结构，这是对权矩阵物理意义的一种全新的认识，为发挥权矩阵在线性最优控制中的作用提供了又一途径。文中还用该方法设计了一降阶反馈附加励磁控制系统，收到良好效果。 |
| 英文摘要 |
| This paper ingeniously combines linear optimal control theory, sensitivity analysis and linear program to overcome the difficulty of choosing optimal weighting matrices. It is pointed out that the optimal choice of weighting matrices not only improves the control system dynamic qualities but also simplifies the structure of control system. This is a completely new knowledge of the physical meaning of weighting matrices, and also gives another way to make good use of weighting matrices in linear optimal control strategies. As a practical example, an optimal supplementary excitation control system is designed by the proposed method and satisfactory results were reached. |
