摘　　要：为提升大型风电的使用寿命,降低齿轮传动运行振动速度,提出大型风电增速箱多级齿轮传动自动安全控制方法。根据行星齿轮传动构建多级齿轮扭转模型,以齿轮传动时产生的振动加速度误差及误差变化率作为模糊PD控制器输入数据,通过计算比例、微分系数,得到多级齿轮传动控制量。使用非线性跟踪微分器对模糊PD控制器进行优化,增加模糊PD控制器的抗噪声能力,进一步提升控制的准确性。实验结果表明,采用该方法控制后,多级齿轮抖动速度得到降低,且齿轮间的动态接触可以在长时间内保持最佳区间。由此证明,该方法能够有效提升大型风电的使用寿命,为工程实际应用提供技术支持。In order to prolong the service life of large-scale wind power and reduce the vibration speed of gear transmission,an automatic safety control method of multi-stage gear transmission for large-scale wind power gearbox is proposed.According to the planetary gear transmission,the multi-stage gear torsion model is constructed.The vibration acceleration error and error change rate generated during gear transmission are used as the input data of fuzzy PD controller,and the control quantity of multi-stage gear transmission is obtained by calculating the proportional and differential coefficients.The nonlinear tracking differentiator is used to optimize the fuzzy PD controller,which increases the anti-noise ability of the fuzzy PD controller and further improves the control accuracy.The experimental results show that the jitter speed of multi-stage gears is reduced and the dynamic contact between gears can maintain the optimal range for a long time after this method is adopted.It is proved that this method can effectively prolong the service life of large-scale wind power and provide technical support for practical engineering application.
