摘　　要：对于同时装备主动稳定杆与主动前轮转向的车辆,为了获得最佳控制性能,建立仿真模型研究了双系统的耦合问题.建立非线性车辆动力学模型,并设计了主动转向比例积分微分控制器;基于稳定杆作动器,设计了主动侧倾滑模控制器以及反侧倾力矩前后轴分配模糊控制器;最后设置阶跃转向与双移线机动工况.仿真结果表明,主动转向可以一定程度改善侧倾性能;另一方面,反侧倾力矩分配与主动转向配合可以进一步提高车辆的横摆稳定性能,同时还可以保证侧倾稳定性能.To achieve an optimal control performance for the vehicles equipped with Active Stabilizer-bar and Active Front-wheel Steering,a coupling problem was researched with simulation.Firstly,a nonlinear vehicle dynamic model was established,and an active steering PID controller was designed.Then,based on the stabilizer-bar actuators,an active roll sliding mode controller and an anti-roll moment distribution fuzzy controller between front and rear axle were designed.Finally,the step steering and double-lane-change maneuver were simulated and analyzed.The simulation results show that the active steering can improve the roll performance,and the dynamic distribution and active steering can further improve the yaw stability,and guarantee the roll stability performance.
