| 摘 要： | 针对汽车主动前轮转向(AFS)与直接横摆力矩(DYC)协调控制问题,提出了一种基于模型预测控制的集成控制算法。该算法采用分层集成控制结构,设计了模型预测控制器,研究了二次规划轮胎力分配法,并通过仿真实验对算法进行验证。结果表明:控制算法能够提高车辆的稳定性,具有可行性;采用二次规划轮胎力分配法相对于单轮制动轮胎力分配法可扩大稳定性控制范围。

| Abstract: | For vehicle AFS and DYC coordination control problem,an integrated control algorithm based on model predictive control is proposed in this paper.The algorithm adopts hierarchical integrated control structure.The model predictive controller is designed and quadric programming method is used for tire force allocation.The simulation is used to verify the algorithm.The result shows that the algorithm can enhance the vehicle stability and is feasible.The tire force allocation by quadratic programming method with regard to a single wheel brake force allocation method can extend stability control range more. |
