INA法中动态预补偿器的一种新的结构

A New Structure of Dynamic Precompensator in Using Inverse Nyquist Array Method

本文就逆乃氏阵列法(INA法)中难以设计动态预补偿器问题,提出了用V规范网络结构代替通常采用的p规范网结构的预补偿器。避免了对动态阵K^(-1)(s)求逆使所设计的动态补偿器具有结构简单易于实现的特点,从而将INA法推广应用到只有用动态补偿器才能实现对角优势的场合。

The problem we studied here is how to design a dynamic compensator in using INA method. H.H. Eosenbrock and M.P. Ford et al. have pointed out it is difficult to do it. In order to obtain K(s)we have to invert the dynamic matrix K^(-1)(s) which has been obtained by some method It would make K(s)very complexity and probably unstability. The method presented here is very simple. We use compensator with V canonical form instead of general p canonical form, then the problem can be solved easily. That is, when using compensator with V canonical form, we can extend INA method to the case when we have to use dynamic compensator,
