具有线性前馈环节的MRACS设计方法

Design Method of MRACS With Linear Feedforward Loop

针对ＭＲＡＣＳ采用正反馈环的设计方法所存在的局限性，提出一种用线性前馈环节取代正反馈环节的新的设计方法．该方法不受模型相对阶数的限制，拓宽了使用范围，不仅简化了系统的结构，而且提高了系统的抗噪声能力．

In this paper a new method for resolving the limit of the right feedback in MRACS isbrought up.In this method, the right feedback drcuit is replaced by a linear fed aheadcircuit.The method expands the used range to any relative rank of the mold.The methodnot only makes the constriction very simple but also increases the anti-disturbance ability ofthe system.
