摘要
局部高放系统是用高阶导数组成的反馈回路抑制干扰,非线性及变参数的影响,从而使低阶导数和位置反馈回路的性能得到改进,局部高放回路增益易调高。文中讨论了允许无穷增益的条件,结合机电装置有干摩擦的控制对象讨论了用局部高放系统抑制干摩擦的影响。最小速度限和精度及与增益的关系,文中给出了实际例子。
The local great-gain control system is a feedback system with high order derivatives. It can be used to restrain the perturbance, nonlinearity and parameter variation. The conditions of system infiniture gain was discussed. It's application to turn-table control system with friction was illustrated. The minimum velocity and system predsion concerning the gain was discussed. An example was given.
