本文介绍了一种频率加权控制器降阶方案，该方案在降阶控制器的使用下具有良好的闭环系统稳定性。通过将控制器的稳定分数表示与考虑闭环系统稳定裕度的降阶过程中的频率加权相结合，我们利用Bezout恒等式简化了频率加权控制器的降阶过程。文中还给出了一些算例来说明归约过程。
This paper introduces a frequency-weighted controller reduction scheme which offers good closed-loop stability under use of the reduced order controller. By combining the use of a stable fractional representation of the controller with a frequency weighting in the reduction procedure derived by consideration of the closed-loop stability margin, we formulate a frequency-weighted controller reduction procedure with the weight simplified by the Bezout identity. Some examples are used to illustrate the reduction procedure.
