摘要： 为实现滩涂贝类采捕机的路径跟踪控制，设计了一种可按照预设采捕路线进行路径跟踪的控制系统。以履带式滩涂贝类采捕机为研究对象，在高斯平面坐标系建立了采捕机转向运动学模型，设计了一套带修正因子的模糊控制系统，在实际滩涂作业环境进行了控制参数标定试验，并在Matlab/Simulink中搭建了仿真控制模型，对常规模糊控制和带修正因子的模糊控制进行对比分析。仿真结果表明：当采捕机作业速度为0.02 m/s和0.03 m/s时，带修正因子的模糊控制较常规模糊控制系统导航精度分别提升了2/3和1/3，控制时间分别缩短44.44%和35.71%，证明了该系统具有较好的路径跟踪控制效果，为滩涂贝类采捕机路径跟踪提供了技术参考。

Abstract:

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.
