Target spraying system control method and device based on fuzzy PID and storage medium

The invention discloses a target spraying system control method and device based on fuzzy PID and a storage medium. The target spraying system comprises a camera, an electromagnetic valve and a fuzzyPID controller, and the fuzzy PID controller is electrically connected with the electromagnetic valve. The control method comprises the steps of acquiring a weed image acquired by the camera, acquiring weed density information through a preset image recognition algorithm, acquiring the current spraying flow of the electromagnetic valve, reading a target spraying flow from a database according to the weed density information, obtaining a flow difference value and difference value change rate information according to the current spraying flow and the target spraying flow, sending the flow difference value and the difference value change rate information to the fuzzy PID controller, acquiring PID control parameters output by the fuzzy PID controller, and adjusting the spraying flow of the electromagnetic valve accord
