中文摘要:
      为了提高农业机械导航精度,在纯追踪算法的基础上,设计了两步纯追踪航向校正模型算法,通过校正车体的航 向角,减小车体的横向误差。在MATLAB环境下仿真结果表明,该算法比纯追踪算法的精度高,最大误差和标准差均有 所减小。在4轮电动车上,搭建液压系统和卫星接收系统,进行现场试验,验证了两步纯追踪航向校正模型算法的可行 性和有效性。
英文摘要:
      On the basis of pure pursuit algorithm analysis published or used in recently years, a model of two-step pure pursuit course correction algorithm was designed, vehicle heading angle was corrected, thereby reducing the lateral error of the vehicle body. The simulation results under Matlab show that the algorithm is more accurate than the pure pursuit algorithm, and the maximum error and standard deviation are all reduced. In the four-wheel electric car. a set of hydraulic system and a set of satellite receiving systems were built. and the algorithm field test was carried out to verify the feasibility and effectiveness.
