控制系统输出至X的输出反馈解耦──积分型解耦的对偶性

Feedback Decoupling or System Output to x─duality of integral form decoupling

针对状态反馈加前置比例补偿对系统进行解耦的充分必要条件及积分型解耦方法，提出了采用输出至Ｘ的输出反馈加本文定义的环内后置比例补偿对系统进行解耦的充分必要条件积分型解耦方法。克服了状态反馈在许多时候要设计观测器；避免了对部分系统进行对角优势解耦，具有一定的理论和实用价值。

In view of the sufficient and necessary conditions of decoupling for control system using state feedback plus forward proportional compensation, a integralmode decoupling method by using output feedback from output to x plus inside-loop rearwad proportional compensation is proposed;with which the design of static observer and the digonal dominant decoupling work necessary in common used methods can be omitted.
