  Abstract
  A permanent magnet linear synchronous motor (PMLSM) digital signal processor-based drive including both sliding-mode controller and fuzzy deadzone estimator is developed to steer the mover position of the PMLSM. The sliding-mode controller with integral operation will provide properties of fast response and insensitive to parameter variations and external disturbance. By utilizing the concept of deadzone compensation to eliminate steady-state errors, the fuzzy deadzone estimator will overcome the problem resulting from the unknown upper bound of lumped uncertainty in sliding-mode control. Finally, the effectiveness of the proposed control schemes is demonstrated by experimental results of tracking square-wave and sinusoidal reference trajectories.
