摘要
在进行风电机组叶片表面打磨工序时,需要控制打磨头的径向与叶片表面保持垂直.对打磨头的角度调整问题进行分析和研究,通过分析打磨头的结构构成与运动轨迹,建立打磨头伺服系统的数学模型.基于角度变化引起的重力转矩补偿量,提出一种模糊比例-积分-微分(Proportion-Integral-Differential,PID)的角度伺服控制系统.Simulink仿真验证结果表明,重力补偿后模糊PID控制方法的打磨头伺服系统响应速度更快、误差更小,能够较好地调整打磨头的角度.
Abstract
When grinding the blade surface of the wind turbine,it is necessary to control the radial of the grinding head and the blade surface to keep vertical.The problem of Angle adjustment of grinding head is analyzed and studied.The mathematical model of grinding head servo system is established by analyzing the structure and movement trajectory of grinding head.A fuzzy Proportional-Integral-Differential(PID)Angle servo control system is proposed based on the compensation of gravity torque caused by Angle change.The simulation results of Simulink show that the servo system with fuzzy PID control method after gravity compensation has faster response speed and smaller error,and can realize the angle adjustment of the grinding head well.
