摘　　要：空中树障清理装置的刀具在清理切削线路附近的树障时,不可避免的会出现负载突变情况。传统的方法通常是在刀具电机调速系统中应用双闭环控制策略,但该控制方法在实际工作中会出现适应性和稳定性差等劣势,而且在设置一定转速负载突变会引发Windup现象,使得空中树障清理装置无法正常工作。基于此,为避免树障清理装置清理过程中出现Windup现象,论文在传统的电流环控制的基础上增加Anti-Windup电流环控制器,解决了传统电流控制环中积分饱和的问题。在传统的PID转速环控制中加入了模糊控制,建立了模糊控制PID转速调节器,提高了树障清理装置调速系统的自适应能力。最后验证分析改进的树障清理装置调速系统的性能,仿真计算结果表明,设计的空中树障清理装置调速系统具有较强的抗扰动能力,扰动后能够快速恢复,设定的转速突变时系统具有较强的动态响应跟随性,能够满足实际树障清理工程需求。The tool of the aerial tree obstacle cleaning device inevitably experiences sudden load changes when cleaning tree obstacles near the cutting line.The traditional method usually applies a dual closed-loop control strategy in the tool motor speed control system,but this control method may have disadvantages such as poor adaptability and stability in practical work,and a sudden change in load at a certain speed can cause Windup phenomenon,making the aerial tree obstacle cleaning device unable to work properly.Based on this,in order to avoid the Windup phenomenon during the cleaning process of the tree obstacle cleaning device,the paper adds an Anti Windup current loop controller on the basis of traditional current loop control,solving the problem of integral saturation in the traditional current control loop.Fuzzy control has been added to the traditional PID speed loop control,and a fuzzy control PID speed regulator has been established to improve the adaptive ability of the speed control system of the tree obstacle cleaning device.Finally,the performance of the improved tree obstacle cleaning device speed control system was verified and analyzed.The simulation results showed that the designed air tree obstacle cleaning device speed control system has strong anti-interference ability,can quickly recover after disturbance,and has strong dynamic response following ability when the set speed suddenly changes,which can meet the actual requirements of tree obstacle cleaning engineering.
