| 摘 要： | 将H∞理论的混合灵敏度指标融入到特征结构配置中, 将混合灵敏度指标转换为特征结构设计参数的函数关系, 建立了特征结构配置的频率域指标约束. 这两种方法的结合各自利用了其在时域和频率域的设计优势. 通过优化算法所获得的鲁棒特征结构配置, 既保证了闭环特征值/特征向量, 又使反馈回路具有一定的频率域特性. 计算实例表明这种综合设计方法的有效性.

| Abstract: | A method is proposed to combine eigenstructure assignment (EA) with mixed-sensitivity H-infinity. EA is a time domain technique while H/-infinity is a frequency domain one. The mixed-sensitivity problem can be translated analytically into function of EA design parameters. The integrated method makes the best of individual advantage in time domain (EA) and frequency domain (H-infinity). By using optimization technique, the resulting robust EA can obtain both desired locations of closed-loop eigenvalues and loop shapes in frequency domain. The case study shows the effectiveness of the design method. |
