现有车辆自适应巡航控制多专注于单一的轨迹跟踪目标,而决定控制技术实际应用效益的关键是系统的节能性能.为了能够同时保证跟踪误差收敛性与燃油经济性,研究了一种车辆节能自适应巡航控制器设计方法:首先以轨迹跟踪为目标,设计了具有时变反馈增益的状态反馈控制律;其次,以反馈增益为优化变量,以整个预测时域内各采样时刻自身车辆单位位移燃油消耗量的累加为代价函数,基于经济模型预测控制方法设计了节能控制算法,并通过构建共同Lyapunov函数,给出了保证跟踪误差以指数速度收敛的反馈增益选取范围;最后,通过数值仿真验证了控制器设计的有效性,定量展示了本文所提出的方法在降低燃油消耗量方面的有效性.
Study on Energy-saving Adaptive Cruise Control for ICVs
The existing vehicle adaptive cruise control mostly focuses on a single trajectory tracking target,and the key to determin the practical application benefit of the control technology is the energy-saving performance of the system.In order to ensure the tracking error's convergence and fuel economy at the same time,this paper studies a design method forof vehicle energy-saving adaptive cruise controller.Firstly,a state feedback control law with time-varying feedback gains is designed with trajectory tracking as the goal.Secondly,taking the feedback gain as the optimization variable and the accumulation of the fuel consumption per unit displacement of the own vehicle at each sampling time in the entire prediction time domain as the cost function,an energy-saving control algorithm is designed based on the economic model predictive control method,and the selection range of the feedback gain to ensure that the tracking error converges at an exponential speed is proposed.Finally,the effectiveness of the controller design is verified by numerical simulations,and the effectiveness of the method proposed in this paper in reducing fuel consumption is quantitatively demonstrated.
