| Abstract: | In order to improve servo accuracy of NC machine tool feeding system,a method of vector control was put forward for servo-motor control and the mathematical model of AC servo system was set up.Research result showed that this method has remarkably enhanced the linearity of the motor's mechanical characteristics and improved its starting torque,making the controlling effect of AC motor similar to that of DC one.The preliminary analysis work of dynamic and static performances of the servo system could be comp... |
