A scheme of vehicle sideslip angle observer based on finite time convergent

汽车质心侧偏角估计对于车辆稳定系统的设计具有重要的意义,而车辆稳定系统本质上来说是一个实时系统,为了从理论上保证汽车质心侧偏角估计值的有效性,文中设计了具有有限时间收敛的观测器方案,并通过ve DYNA汽车性能仿真平台对算法的有效性进行了验证,结果表明该方案能迅速有效地跟随汽车质心侧偏角真实变化,达到预期效果。

An efficient vehicle sideslip angle observer is important for vehicle electric stability control system, and vehicle stability system is a real-time system essentially. In order to guarantee the effectiveness of vehicle sideslip angle estimation value theoretically, a scheme observer based on finite time convergent was designed. The effectiveness of the algorithm is verified through the performance simulation platform ve DYNA, experimental results show that the scheme can follow the real change of vehicle sideslip angle quickly and effectively, and expected effect is attained.
