中文摘要

      在控制系统的频率域设计方法中，最为关键的一步是预期开环特征函数（矩阵）Ｑ（s）的选择，这是一个极为重要但又通常被忽略的问题．本文讨论了Ｑ（s）的选择对控制系统的静动态性能，鲁棒性及所得控制器的可实现性和简单性等的影响．

英文摘要

      For the frequency domain design methods of control systems，the most critical step is to choose the required open-loop transfer function (matrix) Q(s). This problem is very important but often be neglected. This paper discusses the influences of the choice of Q (s) to the static and dynamic performance，robustness，the realizability and the simplicity of the obtained controllers of control systems.
