| 摘 要： | 讨论了输入多采样率状态反馈鲁棒极点配置问题。由于输入多采样率采样，增加了系统的实际输入的个数，使得实现极点配置的状态反馈控制系统中具有自由度。现将这一自由度明确地表示为自由参数的形式，并利用优化算法选择这些参数，增强闭环系统的鲁棒性。

| Abstract: | This paper discusses the problem of robust pole assignment using multirate input sampling state feedback. Because of the multirate input sampling, the actual input number of a system is increased, enabling the pole assignment state feedback controller to have some degree of freedom. In this paper, the degree of freedom is explicitly expressed as free parameters in form. These free parameters are selected by an optimization algorithm, and can be utilized to improve the robust performances of closed loop systems. |
