摘　　要：针对车载式施药机高精度喷药需求,介绍了以伺服电机为执行元件的精准喷药伺服系统,该系统在电流闭环、速度闭环、位置闭环综合控制下,可以在稳定闭环控制的情况下实现较高的带宽。通过系统建模及位置环仿真分析,该系统反应灵敏,可达到2Hz左右,为大带宽车载式喷药机的工程设计提供了借鉴。Aiming at the demand of high precision spraying of vehicle mounted sprayer,this paper introduces a precise spraying servo system with servo motor as the executive component.Under the comprehensive control of current closed-loop,speed closed-loop and position closed-loop,the system can achieve higher bandwidth under stable closed-loop control.Through the system modeling and position loop simulation analysis,the system is sensitive and can reach about 2Hz,which provides a reference for the engineering design of large bandwidth vehicle mounted sprayer.
