| 摘 要： | 建立了包含车身侧倾特性的车载式火炮多桥转向三自由度模型动力学方程普适公式,并构造了用于重构车辆状态的降维观测器,设计了基于最优跟踪控制策略的车辆转向控制器。分析结果表明,能够通过控制车辆后轮转向角来减小汽车瞬时出现的过多转向或不足转向,增强了汽车的动态转向稳定性。所构造的降维观测器也能使反映车辆操纵性能的车辆状态量估计值与实际值一致。

| Abstract: | Dynamic equations of a 3 degree-of-freedom model for the multi-axle steering system of the truck-howitzer including the vehicle body side-sway characteristic was derived,a dimension reduction observer for rebuilding the vehicle state was constructed,and a vehicle steering controller based on the optimal tracking strategy was designed.The analysis results showed that the instantaneous oversteering or understeering of the vehicle can be reduced by the control of the rear-wheel steering angle to enhance the dynamic steering stability.The constructed dimension reduction observer can estimate the vehicle state parameters depicting its steering performance in good agreement with the actual ones. |
