中文摘要	An active disturbance rejection controller was developed to improve tracking accuracy and disturbance rejection ability of fast tool servos in noncircular turning. In the linear actuator model, the nonlinear part of the model was modeled as an internal disturbance and the cutting force was regarded as an external disturbance. An extended state observer was designed to produce real-time estimates and compensation for the total disturbance. Simulations show that the controller is better than a PID controller. The controller was implemented using digital signal processor programming for noncircular turning, and machining results demonstrate that controller provide good controllability and tracking errors less than +/-5 mu m.
