Research on Sprayer Boom Modeling and Control of Plant Protection Machine

In order to suppress the elastic deformation of the boom in the vertical direction, the finite element model of the boom was established based on the ANSYS platform and the numerical modal analysis was carried out. According to the established model, the kinematic modeling and vibration analysis of the sprayer of the plant protection machine showed that the deformation of the end of the spray boom was the maximum. In this paper, the root of the boom is selected as the point of application, the control law is established by the quadratic optimal control theory, and the optimal controller is designed to effectively suppress the vertical elastic deformation of the boom, which provides the theoretical basis for the project implementation.
