| 英文摘要 |
| This paper deals with the variable structure control of high speed milling spindle supported by active magnetic bearings (AMB-spindle). The plant model consists of electromagnetic actuators, spindle dynamics and high speed cutting process. The discrete time variable structure controller (VSC) is designed to attenuate the spindle vibration caused by the cutting process and other disturbances. Simulations show that the VSC strategy is robust against external disturbances and model perturbation. In comparison with the PID controllers, the VSC also enables a satisfactory dynamic performance to be achieved in terms of variation in depth of cut. |
