| 摘 要： | 将一种参数在线自校正模糊控制器引入数控机床交流伺服系统中，该控制器可以根据测量得到的偏差E及偏差的变化率EC在线自动整定PID控制器的三个参数，采用上述方法后，可以显著提高控制系统的精度。大大降低跟踪误差，实验结果表明，这是一种切实可行的控制方法。

| Abstract: | A fuzzy controller with self-tuning parameter was implemented in the AC servo system of numerically controlled machine tools in this paper. This controller is capable of automatically adjusting the three parameter of PID controller according to the tracking error E and the change in error EC. The control accuracy can be improved greatly in AC servo control system .and the following error can be reduced substantially. The experimental result shown the control method is available for AC servo control system. |
