Abstract :
An adaptive model tracking controller is designed which can be applied to AC servo systems in Numerical Control(NC) machine to improve machining accuracy. The influences of parameter variation and external disturbances can be compensated by the controller based on model reference adaptive control. Simulation results show that, compared with conventional systems, systems with the designed controller have better consistency when parameters variation and external disturbances exist.
