| 摘 要： | 跟踪性能是伺服系统的本质性能,前馈控制是提高交流伺服系统跟踪性能的一种有效手段。在速度前馈的基础上,研究了在转矩闭环的给定信号上增加转矩前馈的新型前馈控制结构,以提高伺服系统的位置跟踪性能。实验结果显示该控制结构大幅度地减小了交流伺服系统梯形响应或S曲线响应中的加减速段的位置跟踪误差。

| Abstract: | The tracking performance is the essential performance of the servo system.Feedforward control is an effective means to improve tracking performance of AC servo system.A new kind of feedforward control structure,in which torque feedforward is added to the reference signal of the torque close-loop based on velocity feedforward control was proposed.The experiment results prove that the position tracking performance in the process of acceleration and decceleration is improved markedly. |
