Abstract
A dynamic model including non-idealities for a permanent magnet linear synchronous motor (PMLSM) is postulated and verified. The non-idealities acting on the physical linear motor are measured and analyzed. These experimental results are utilized in the model. The verified simulation model is used in developing a force disturbance compensator for the velocity controller of the motor. The force non-idealities, such as the cogging force, friction and load force variation, are estimated using a disturbance observer. The acceleration signal in the observer is derived through the use of a low-acceleration estimator. The significant effects of the disturbance compensator on the simulated and measured dynamics of the motor are shown.
