TTo realize the path tracking control of tidal flat shellfish harvester, a control system was designed, which can follow the prearranged collecting route. in this paper, the crawler-type tidal flat shellfish harvester was taken as the research object, and the steering kinematics model of the crawler-type shellfish harvester was established in the Gauss plane coordinate system, and a fuzzy control system with correction factor was designed, the control parameter calibration experiment was carried out in the actual tidal flat environment, the simulation control model was built by Matlab/Simulink, and the comparison between the conventional fuzzy control and the fuzzy control with correction factor were analyzed. The simulation results showed that the navigation precision of the fuzzy control system with correction factor is improved by 2/3 and 1/3, the control time is shortened by 44.44% and 35.71%, respectively, compared with the conventional fuzzy control system when the working speed of the harvester is 0.02 m/s and 0.03 m/s. 

It proved that the algorithm has a good effect of path tracking control and provides a technical reference for path tracking of tidal flat shellfish harvester.
