在许多场合中高速重载缸下行的过冲现象会严重影响设备的使用性能，有时是不许可的，采用控制手段可有效地解决这一问题。本文提出采用一步预测控制方法解决高速重载缸下行过冲问题，实验结果表明这种方法可有效地抑制过冲，提高返程速度。
In many occasions, the overshooting phenomenon of the high-speed heavy-duty cylinder descending cylinder will seriously affect the serviceability of the equipment, sometimes it is not permissible. The control method can effectively solve this problem. In this paper, a one-step predictive control method is proposed to solve the problem of down-overshooting in high-speed heavy-duty cylinders. The experimental results show that this method can effectively suppress overshoot and improve the return speed.
