新能源驱动农机电气自动化系统设计与优化OA

In response to the problems of inaccurate power output matching,low energy utilization efficiency,insufficient coordination control between batteries and motors,poor adaptability to job load fluctuations,and insufficient safety pro-tection and automation regulation capabilities of the electrical system of new energy driven agricultural machinery under complex field conditions,this paper adopts the method of"multi-source state perception vehicle controller centralized decision-making motor drive closed-loop regulation battery energy collaborative management",using the power batter-y pack The BMS battery management system,vehicle controller,motor controller,drive motor,job execution mecha-nism,and sensing detection module are at the core.By collecting battery SOC,voltage,current,motor speed,job load,driving speed,and key component operating status,comprehensive control of agricultural machinery walking drive,job power output,energy distribution,and safety protection is achieved.Through vehicle speed feedback,load compensation and PID closed-loop control,the motor output can be dynamically matched with the operating load,thereby improving the operating stability and adaptability of new-energy agricultural machinery under complex field conditions.
