A water pump flow control method, a water pump control system and an agricultural unmanned aerial vehicle are disclosed, the method comprising: acquiring a flow control instruction of a water pump, the flow control instruction being generated based on a desired flow of the water pump; generating a rotating speed control instruction of a water pump motor according to the flow control instruction, and controlling the motor of the water pump to work; when the water pump motor works, the first actual flow, measured by the flowmeter, of the water pump is obtained in real time; the rotating speed ofthe water pump is adjusted according to the first actual flow and the expected flow, so that the flow of the water pump reaches second actual flow, wherein the absolute value of the difference between the second actual flow and the expected flow is smaller than the preset value. The method can accurately control the flow of the water pump in various pesticide application scenes.
一种水泵流量的控制方法、水泵控制系统和农业无人飞行器,该方法包括:获取水泵的流量控制指令,流量控制指令基于水泵的期望流量而生成;根据流量控制指令,生成水泵电机的转速控制指令,控制水泵的电机工作;在水泵电机工作时,实时获取流量计测量得到的水泵的第一实际流量;根据第一实际流量与期望流量,调节水泵的转速,以使水泵的流量达到第二实际流量,第二实际流量与期望流量的差值的绝对值小于预设值。该方法可在各种农药施用场景下精确控制水泵的流量。
