摘要

研究了具有时间加权性能指标的最优离散线性时不变系统的设计。导出了保证所有闭环极点位于H区域内并使时间加权性能指标最小的最优状态反馈控制律。区域H可以是任何以线段和/或二次曲线为界的区域。性能指标由两部分组成，一部分用于惩罚持续误差，另一部分用于提高闭环系统的鲁棒性。通过实例说明了所提方法的有效性和适用性。

Optimal regional poles placement with time-weighted performance index

The design of optimal discrete-time linear time-invariant systems with time-weighted performance index is studied. The optimal state feedback control law, that ensures all closed-loop poles lie inside a region H and minimizes a time-weighted performance index, is derived. The region H could be any region bounded by line segments and/or quadratic curves. The performance index consists of two parts, namely, one part is used to penalize the sustained error, while the other part is used to improve the robustness of the closed-loop system. Illustrative examples are included to demonstrate the validity and applicability of the proposed method.<>
