Short summary
Aiming at the problems of speed ripple, slow response, sensor dependence, and mechanical chattering in the motion of the permanent magnet linear synchronous motor (PMSLM), a model-free speed control system based on the model reference adaptive system (MRAS) is proposed in this paper. The control system designed in this paper has reference value for the system control structure of the PMSLM.
