本文根据二次调节静液传动系统给出了位置系统方框图,并根据实际情况将位置系统简化为三阶系统,对位置闭环控制系统采用了PID控制并进行了试验研究。结果表明,采用PID控制对二次调节静液传动闭环位置系统能取得较好的控制效果。
In this paper, the block diagram of the position system is given according to the secondary regulation hydrostatic transmission system. The position system is simplified to the third-order system according to the actual situation. PID control is adopted for the position closed-loop control system and the experimental study is carried out. The results show that the PID control can achieve better control effect on the secondary adjustment of the closed loop position system of hydrostatic transmission.
