极点配置的 H∞ 设计方法不但能满足系统的 H∞ 性能要求 ,而且能使闭环极点配置在希望的范围内 ,因而使系统具有满意的阻尼比 ,同时也避免了过快的控制器动态对设备产生的冲击。针对直升机 H∞ 控制器设计中遇到的问题 ,如控制器结构的选择、加权矩阵的选择以及如何考虑不确定性等进行了研究。通过对 CH-4 7直升机设计结果的数值仿真 ,表明所设计的系统达到了 ADS-33水平 1的性能要求和鲁棒稳定性要求 The pole configuration H∞ design not only meets the H∞ performance requirements of the system, but also enables the closed-loop poles to be placed within the desired range, resulting in a satisfactory damping ratio of the system while avoiding excessive dynamic controller dynamics Impact generated. The problems encountered in the design of helicopter H∞ controller are studied, such as the choice of controller structure, the selection of weighting matrix and how to consider the uncertainty. Through the numerical simulation of the results of CH-47 helicopter design, it shows that the designed system meets the performance requirements and robustness requirements of ADS-33 Level 1
