摘要: 无人车路径跟踪控制是自动驾驶领域的关键技术之一,选择轮毂电机驱动无人车作为研究对象,设计了一种预瞄时间自适应的路径跟踪控制器。首先,建立了二自由度单轨的理想自行车模型;其次,基于模型预测控制算法,设计了预瞄时间固定的无人车路径跟踪控制器,计算了跟踪参考路径所需的前轮转角;在此基础上,基于模糊控制原理,设计了预瞄时间自适应的无人车路径跟踪控制器;通过MATLAB/Simulink仿真验证,结果表明:与预瞄时间固定的控制器相比,预瞄时间自适应的控制器的横向偏差降低了21.5%,横摆角偏差降低了17.2%,具有更高的路径跟踪精度。

Abstract: The path tracking control of unmanned vehicle is one of the key technologies in the field of autonomous driving. The hub motor driven unmanned vehicle was selected as the research object, and a path tracking controller with adaptive preview time was designed. Firstly, the ideal autonomous vehicle model of two-degree-of-freedom monorail was established. Secondly, based on the model predictive control algorithm, a path tracking controller of unmanned vehicle with fixed preview time was designed, and the front wheel angle required for tracking the reference path was calculated. On this basis, based on the fuzzy control principle, a path tracking controller of unmanned vehicle with adaptive pre-view time was designed. Through the verification of MATLAB/Simulink simulation, the results show that compared with the controller with fixed preview time, the controller with adaptive preview time reduces the lateral deviation by 21.5% and the yaw angle deviation by 17.2% and has higher path tracking accuracy.
