摘要
本文指出可把摩擦力引起的死区非线性视为正比于单位速度向量的反馈,并建立了有巨大摩擦力的电炉电极控制液压伺服系统的方框图及传递函数,以脉冲响应法对之进行了辨识。辨识结果与实际一致。
This paper points out that the nonlinearity of the dead zone due to the frictional force can be considered as the feedback directly proportional to unit velocity vector. And it sets up the block diagram and transfer function of electric furnace-electrode controlled hydraulic servo system. The identification is carried out by impulse response method and its identified result conforms with actuality.
