摘要

针对多变量频域Nyquist类设计法中的Hawkins伪对角化法，给出了一种改进的动态伪对角化方法来提高系统的对角优势度以改善系统的解耦性与鲁棒性并进行了相关分析.最后将这种动态伪对角化方法用于某型航空发动机稳态控制器的设计，仿真结果表明：相较于标准Hawkins法，改进的动态伪对角化所给出的补偿系统具有较好的动静态解耦性与鲁棒性.

Abstract

For Hawkins's pseudodiagonalization method in multivariable Nyquist-class frequency domain design

an improved dynamic pseudodiagonalization method was presented to enhance the diagonal dominance of the system in order to improve the decoupling and robustness of the system together with relevant analysis. Finally

the dynamic pseudodiagonalization method was used to design an aero-engine steady controller. The simulation results show that the compensated system given by improved dynamic pseudodiagonalization method has good dynamic and static decoupling and robustness compared with standard Hawkins's method.
