实现对角优势的V规范预补偿器的伯德图设计法

Body-Diagram Design Method for Diagonal Dominance Based on Canonical Form Precompensator

多变量系统Ｎｙｑｕｉｓｔ阵列法的核心是设计一个预补偿器，使补偿后的系统为对角优势．本文所提出的Ｖ规范补偿网络的伯德图设计法，对预补偿器的设计是逐元进行的，与传统的逐列（或逐行）设计法相比，具有更大的灵活性，便于观察整个频段上的补偿效果，得到结构更简单的补偿器，又避免了大量的计算．

How to design a physically realizable precompensator to make the transfer matrixdiagonal dominance is the key step in MNA technique.In this paper we proposes a new design method. Bode-diagram method based on V canonical form precompensator.the design process provides insight into the effect of compensation on dominance over a wide frequency range,so we can easily obtain dynamic compensator which is simple and realizable.
