分布式驱动结构给车辆动力学控制带来机遇和挑战,如何可靠地实现其横向稳定性控制是关键技术。考虑车辆参数的不确定性,提出了基于区域极点配置的轮毂电机驱动汽车横向稳定性控制策略,分析了保性能权重矩阵参数对控制性能的影响;为了能最大限度地利用路面附着能力,利用轮毂电机驱动力和制动力共同产生横摆力矩,并结合驱动模型切换提出了规则化转矩分配控制策略;通过数值仿真和硬件在环仿真开展了控制系统的性能分析。结果表明,所提出的基于区域极点配置的上层控制策略不仅能改善汽车的操纵稳定性,而且对轮胎侧偏刚度等参数不确定性具有较强的鲁棒性;同时,下层规则化转矩分配控制策略能确保在低附...

For the opportunities and challenges brought by the distributed drive structure on vehicle dynamics control, how to reliably realize lateral stability control is the key technology. Considering the uncertainty of vehicle parameters, a lateral stability control strategy of an in-wheel-motored electric vehicle based on the regional pole placement is proposed, and the influence of guaranteed weight parameters on control performance is analyzed. In order to make maximum use of the adhesion ability of the road, the yaw moment is generated by the dri...
