摘　　要：针对车载式施药机的伺服控制单元,介绍了以电机、减速机、齿轮为传动链的驱动形式,对系统的电流环、速度环进行了仿真建模及分析,得到了它们的阶跃特性。最后对有无前馈的两种形式进行了仿真对比分析,结果证明,加入前馈有助于提升系统的跟踪精度。Aiming at the servo control unit of vehicle mounted pesticide applicator,this paper introduces the driving form of motor,reducer and gear as the drive chain,the current loop and speed loop of the system were simulated and analyzed,and their step characteristics were obtained.Finally,the simulation results show that the adding feedforward can improve the tracking accuracy of the system.
