本文提出了按稳定度配置极点的一种方法。该方法把闭环系统的全部极点配置在复平面左半面的一个特定的区域之内,使闭环系统具有预期的稳定度。它定义闭环系统的主极点实部作为目标函数,用最优化方法中的直接搜索法优化搜索反馈矩阵,使其满足对目标函数的要求。此方法不仅可用于能控能观测系统的设计,而且可用于能稳定系统的设计。该方法还具有容易准备和计算时间短等优点。
This paper presents a method of configuring poles by stability. In this method, all the poles of the closed-loop system are arranged in a specific area on the left half of the complex plane, so that the closed-loop system has the expected stability. It defines the real part of the main pole of the closed-loop system as an objective function and optimizes the search feedback matrix by the direct search method in the optimization method so as to satisfy the requirements of the objective function. This method not only can be used to control the design of observing systems, but also can be used to stabilize the system design. The method also has the advantages of easy preparation and short calculation time.
