本文用频城方法分析了用一般微分算子表示的多变量结构无静差系统的性质,给出了内模原理的频域形式,说明了开环系统存在结构无静差补偿器的充分必要条件,提出了设计结构无静差补偿器的方法。
In this paper, the frequency city method is used to analyze the properties of multivariate non-stationary system with general differential operators. The frequency domain form of the internal model principle is given. It is shown that there is no necessary static compensator in the open-loop system Conditions, proposed a method to design a structure without static compensator.
