| 摘 要： | 电机系统的波动力矩是影响精密伺服系统响应精度的一个关键因素，对恒速工作的永磁同步电机系统进行分析并提出了在电机系统控制指令中叠加补偿指令的抑制波动力矩方法，构造了相应的多层前馈神经网络模型，采用改进的BP网络--SPDS算法进行网络训练，实现了波动力矩补偿指令的计算，经样机系统验证得到了满意的波动力矩补偿结果。表明这种补偿构造方法具有良好的工程实用价值。

| Abstract: | The ripple torque of a motor is a key factor having effect on the response precision of the servo system. For a permanent magnet synchronous motor system in constant speed operation, a method is proposed for suppression of the ripple torque by superposing a compensative component in the command input of the motor system, and a corresponding multiplayer feedforward neural network is constructed to produce the compensative component. The neural network is trained by the developed BP network -- SPDS algorithm, satisfiactory experiment results are presented to show the implementation of ripple torque compensation by successfully trained neural network. |
