摘要
在文献[1]中，V·D·Blondel、R·Rupp和H·S·Shairo建立了在控制工程设计的稳定最小位相稳定化问题研究中有着直接应用的关于解析函数的一个定理。本文利用Schot-thy定理及其最新结果改进了这一定理。
In[ 1 ], V. D. Blondel, R. Rupp and H. S. Shapiro proved a theorem, which is on 0 - points and 1 - points of analytic functions of the unit disk and has clase connection to a control engineering design problem, the so - called stable minimum - phase stabilization problem. In the present Paper, the authors improve this theorem by applying Schottky's theorem and recent results on the linear distortion function.
