摘要: 本文介绍一个使用变量叶片泵的电液比例容积调速系统。作者研制了一个带有输出积分器的状态反馈控制器,使用这个控制器可以通过状态变量反馈的方法将系统的极点配置到预定的位置,因此系统的状态性能大为改善,这也为输出积分器消除系统的稳态速度误差创造了条件。

Abstract: The design of an electrohydraulic proportional speed regulating system, using avariable vane pump, is described. The author made a state variable feedback controller with output integrator. With this controller the poles of the system are placed in the pro-determined positions. Thus the system dynamic behaviour is much improved, which lays foundation for the output integrator to secure for a zero steady state error.
