基于模糊PID的智能车辆路径跟踪控制技术研究
Research on Technology of Intelligent Vehicle Path Tracking Control Based on Fuzzy PID
摘要
Abstract
In the research of intelligent vehicle path tracking control,a position error controller is proposed.It is composed of the de-sired yaw rate generator and the fuzzy PID controller. The vehicle's kinematic equation and position error model are established. A virtual path is simulated in the real-time plan between the vehicle mass center and the look-ahead preview point.The change rate of the desired yaw when the vehicle runs along the virtual path is analyzed.Then,the desired yaw rate is obtained by combining the ve-hicle running state with the target tracking path information. Combined with the desired yaw rate generator and fuzzy PID controller, the tracking simulation is realized by using the double lane road as the target path.The simulation results show that the tracking devi-ation mainly occurres in the connection point of the curve road and the straight road and at low speed,the vehicle tracking accuracy is higher,its stability is good, but its poor tracking accuracy and stability occure at middle and high speed.关键词
