基于RL-MPC的智能车辆轨迹跟踪横向控制策略OA
Lateral control strategy for intelligent vehicle trajectory tracking based on RL-MPC
针对智能车辆在横向轨迹跟踪过程中难以兼顾轨迹跟踪精度和行驶稳定性的问题,提出了一种基于强化学习与模型预测控制(Reinforcement Learning with Model Predictive Control,RL-MPC)的智能车辆轨迹跟踪横向控制策略.首先,构建车辆系统动力学模型;然后,依托模型预测控制(Model Predictive Control,MPC)的滚动优化框架实时量化轨迹跟踪精度,同时构建奖励函数,实现控制策略的自主优化,并通过反馈校正模块修正预测偏差;最后,通过Matlab/Simulink软件搭建仿真模型,进行仿真实验,并将RL-MPC控制器与传统MPC控制器进行对比,实验结果表明,在不同工况下,相较传统MPC控制器,RL-MPC控制器对轨迹的跟踪效果更好,并且显著降低了横向轨迹跟踪误差,提升了行驶工况下的操纵稳定性.
To address the problem that intelligent vehicles struggle to balance trajectory tracking accuracy and driving stability during lateral trajectory tracking,a lateral control strategy for intelligent vehicle trajectory tracking based on Reinforcement Learn-ing combined with Model Predictive Control(RL-MPC)is proposed.First,a vehicle system dynamics model is established.Then,relying on the receding horizon optimization framework of Model Predictive Control(MPC),the trajectory tracking accuracy is quantified in real time.Meanwhile,a reward function is constructed to realize the autonomous optimization of the control strate-gy,and a feedback correction module is used to correct the prediction deviation.Finally,a simulation model is built using Matlab/Simulink software for simulation tests,and the RL-MPC controller is compared with the traditional MPC controller.The experi-mental results show that under different working conditions,compared with the traditional MPC controller,the RL-MPC controller achieves better trajectory tracking performance,significantly reduces the lateral tracking error,and improves the handling stability under driving conditions.
