plant external feedback
解釋
電站外反饋-
The innovative ideas in this paper are that robust h control theory based on conventional ip controller is applied to the high - precision feed of a single axis, and the controlled plant is composed of ip velocity loop and two - order model of linear motor. a constraint condition on y in the problem of h2 / h is deduced from the frequency criterion of riccati equation, which makes the repeated computation on r simple. considering the two - loops control problem, the h state feedback controller based on ip controller as the inner controller is applied to satisfy the velocity performance of the system, and a pi controller, the external controller, is used to satisfy the position performance
本文的創新之處在於將傳統的ip速度控制器和直線電動機的二階模型作為一個廣義的被控對象，利用魯棒h _控制理論設計了一個h _狀態反饋控制器，以此解決高精度進給的控制問題，並在此基礎上研究了h _ 2 h _混合控制問題，結合h _代數riccati方程正定鎮定解存在的頻率判據，推出了一個控制器存在的約束條件，使以往須反復試探的，有了更進一步的約束范圍，簡化了計算。
