| Abstract: | Three methods of proportional pressure control on hydraulic presses were introduced and compared,which were open-loop control,closed-loop control based on PID and PID control with addition of initial signals.Results of comparison showe that the closed-loop control algorithm which is added with initial signals has many advantages such as simple control structure,easy debugging operations,stable system and high precision,and etc.The requirements of this hydraulic press on pressure control can be fully satisfi... |
