摘要
分析变频泵控马达速度控制系统的负载特性和负载压力前馈补偿理论,对不同负载工况进行补偿和仿真,提出采用负载压力分段线性补偿法,能够提高变频液压乘人装置的速度稳定性和乘坐舒适感。
The load characteristics of variable frequency pump control motor speed control system and the load pressure feedfor-ward compensation theory were analyzed.The compensation and simulations were made under different load.The load pressure divi-sional linear compensation method was pointed out to improve the speed stability and the ride comfort feel of variable frequency hydrau-lic passenger device.
