摘　　要：针对重型半挂车的侧倾稳定性问题,建立了重型半挂车的动力学模型,并提出了一种基于回路传输恢复技术的LQG主动侧倾控制算法。设计各个车速下LQG控制器,并进行了阶跃转向工况下车辆的仿真。仿真结果表明:LQG主动侧倾控制算法有效提高了重型半挂车的侧倾稳定性。The research sets up a heavy tractor semi - trailer dynamic model and puts forward an active roll control algorithm based on optimal control for the vehicle roll stability control. It also establishes LQG controller in various speeds and simulates roll stability of the vehicle with steering step input. The simulation results show that the active roll control algorithm is very effective in the active roll control for the vehicle.
