摘要
等温锻造液压机工作速度范围要求为0.002mm/s^0.5mm/s,如果用于速度闭环控制的滑块实际工作速度,出现误差或受到外部干扰时,会对等温锻造速度闭环控制造成影响,导致等温锻造控制速度精度和稳定较差。本文给出了利用中值滤波算法对外部干扰信号滤波,实现了对等温锻造液压机超低速的调速控制。并在工控机上通过WinCC组态软件采集、记录速度压制曲线,该控制系统满足了用户的特定需求。
The median fiher algorithm has been adopted to filter the external interference signal in realize the super low speed industrial PC to collect and adjustment of isothermal forging hydraulic press. WinCC software has been the text to used in the record the speed curve. This control system can meet the special requirement of the user.
