Modelling and the Horizontal Elastic Deformation Control for Plant Protection Machine Spray Rod Rigid Frame

Jiqing Chen, Xiangdong Wang, and Shujiang Li
Abstract—In order to reduce the horizontal deformation of large plant protection machine spray rod frame generated during the operation, in the paper, the dynamic model of large plant protection machine spray rod common rigid frame structure in space was established by utilizing the finite element method. And the modal coordinate transformation of it was carried out. Considered in the modal space, finally, the transformed model was translated into state space form. The control of spray rod rigid frame elastic deformation caused by disturbance is realized on the basis of linear quadratic optimal control method. And the simulation was carried out. The simulation results show the validity of the method proposed suppressing the horizontal elastic deformation of spray rod rigid frame. The results of the study provide a method in exploring the elastic deformation inhibition of the plant protection machine rigid frame structure.

Index Terms—Finite element, modal space, elastic deformation, optimal control.
