Load-adaptive cooperative control method and system for electrically-driven double pumps
The invention discloses a load self-adaptive cooperative control method and system for electric drive double pumps. The method comprises the steps that the target flow of a first pump and the target flow of a second pump in the double pumps are obtained; dividing a plurality of rotating speed working points; calculating a steady-state torque corresponding to the rotating speed working point; calculating a motor target torque corresponding to the rotating speed working point; calculating a comprehensive efficiency value; the comprehensive efficiency values are sequentially sorted from high to low, optimal solution screening is sequentially carried out from the motor target torque corresponding to the highest comprehensive efficiency value, the first pump displacement value and the second pump displacement value, and when a preset stepping value range is met, optimal solution screening is carried out; and outputting the motor target torque of the comprehensive efficiency value, the first pump displacement value and the second pump displacement value as final execution target values. The method has the advantages that optimal solution screening is carried out through the comprehensive efficiency value and the stepping value judgment condition, and high system efficiency is obtained on the basis that the system flow requirement is met; the method can reduce the sudden change of the rotating speed of the motor caused by the load change, and improves the responsiveness and stability of the rotating speed.
本发明公开了一种电驱双联泵负载自适应的协同控制方法及系统，获取双联泵中的泵一的目标流量和泵二的目标流量；划分多个转速工作点；计算转速工作点对应的稳态扭矩；计算转速工作点对应的电机目标扭矩；计算综合效率值；将综合效率值从高到低依次进行排序，从综合效率值最高对应的电机目标扭矩和泵一排量取值、泵二排量取值开始依次进行最优解筛选，在满足预设步进值范围时，输出该综合效率值的电机目标转矩和泵一排量取值、泵二排量取值为最终执行的目标值。优点：通过综合效率值以及步进值判定条件进行最优解筛选，在满足系统流量需求的基础上获得较高的系统效率；电机目标扭矩，能够减小负载变化导致的电机转速突变，提高转速响应性和稳定性。
