中凸变椭圆活塞车削伺服刀架控制技术研究

Research on the Control Technology of the Servo Tool Holder for Middle-convex and Varying Ellipse Piston Turning

针对中凸变椭圆活塞数控车削所需的高速伺服技术,开发了满足高速伺服需求的基于工业PC和数字信号处理芯片（DSP）的主从控制结构、采用重复控制系统对直线伺服刀架进行精密控制的系统,获得了良好的性能。

Addressing the high-speed servo technology for the middle-convex and varying ellipse piston numerical control turning machining,a PC-based host-slave control system,with a digital signal processor （DSP） as the slave controller was developed in the need of high-speed servo,and adopting repetitive control methods,servo tool holder was controlled and Good performances have been achieved
