【Abstract】 For the frequency domain design methods of control systems, the most critical step is tochoose the required open-loop transfer function (matrix) Q(s ). This problem is very important but often beneglected. This paper discusses the influenees 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.更多还原
