In order to weaken the influence of the guideway’s random irregularity on the guidance system in high speed maglev train, the guidance controller design considering the random irregularity of guideway was researched. By introducing the structure of the guidance system, the math model was built. Based on the model, the effect of the guideway’s random irregularity on the guidance system was analyzed. Using the optimal control theory and bringing the random irregularity into the performance index, the designing method of the guidance controller considering the random irregularity of guideway was put forward. Indicated by simulation, using this controller, the influence of the guideway’s random irregularity on the guidance system was reduced and expected control performance was gained.
