The computer PID control for electro hydraulic proportional constant presure variable displacementpump with electric feedback is introduced.
介绍了电反馈电液比例恒压变量泵的计算机PID控制。

At the same time, constant engine speed stabilizes output displacement of hydraulic pump and then stabilizes travel speed and vibratory frequency in turn, so that compaction quality is increased.
同时，发动机转速的恒定也使液压泵输出排量稳定，进而保证了行走速度和振动频率的稳定，提高了压实质量。

Additionally, the coordinate principle of variable displacementpump with constant power control and load-sensing control system is demonstrated, and establish the constant power control model.
