摘要:

为解决重型车辆易发生侧翻的问题,提出一种基于快速模型预测的主动安全控制方法.首先,建立重型车辆非线性动力学模型,利用T-S模糊方法将非线性系统转化为线性系统;采用分层控制策略,上层设计模型预测控制(model predictive control,MPC)防侧翻控制器获得最优横摆力矩,下层利用单侧车轮控制方式进行制动力分配.然后,为减少控制器的计算负担,引入Laguerre函数对控制输入序列进行重构,采用原始对偶内点法处理约束条件,实时高效地求解二次规划函数.最后,在典型工况下进行MATLAB/Simulink和TruckSim联合仿真.结果表明,相较于传统MPC控制器,所提的快速MPC控制器能够在保证性能的同时有效提高计算效率,可以及时避免车辆侧翻失稳.

Abstract:

In order to solve the problem that heavy vehicles are prone to rollover, an active safety control method based on fast model prediction was proposed. Firstly, a nonlinear dynamic model of the heavy vehicle was established, and the nonlinear system was transformed into a linear system by the T-S fuzzy method. A hierarchical control strategy was adopted, where the upper layer was designed to obtain the optimal yaw moment by the model predictive control (MPC) anti-rollover controller, and the lower layer utilized the unilateral wheel control method for the allocation of the braking force. Then, in order to reduce the computational burden of the controller, the Laguerre function was introduced to reconstruct the control input sequence, and the constraints were handled by the primal-dual interior point method to solve the quadratic programming function efficiently in real time. Finally, the co-simulation of MATLAB/Simulink and TruckSim was carried out under typical working conditions, and the results show that compared with the traditional MPC controller, the proposed fast MPC controller can effectively improve the computational efficiency while guaranteeing the performance and can avoid the vehicle rollover instability.

Key words: heavy vehicle, model predictive control, Laguerre function, primal-dual interior-point method, rollover stability
