Abstract：This paper adopts Model- Based Disturbance Attenuation (MBDA) method to attenuates external disturbances such as frictional forces, cutting forces, load variations for a permanent magnet linear AC synchronous motor (PMLSM) with high precision and micro -feed. The MBDA uses the nominal plant which is in parallel form with the plant and the output feedback. The error signal, which is the difference between the plant output and the nominal plant output, is fed back through a compensator. (IP) controller is designed in velocity loop so as to meet the requirement of fast tracking and resist disturbance greatly. Simulation results verify that this control method has fast response speed and strong disturbance attenuation, it also can effectively increase processing precision.
