Parameter perturbation, end effect and external interference of AC permanent magnet linear motor affect the accuracy and performance of servo system. In this paper, the PMLSM servo system controller designed by the interval matrix theory is used to solve this problem. The uncertainty of servo system is described by interval matrix. Compared with the precise mathematical model, the controller designed by this theory has strong robustness. The simulation and experiment of the system show that the strategy has excellent dynamic and static performance, it has strong parameter robustness.
