摘要
用CARMA模型控制汽车道路模拟试验台 ,实现汽车试验中的随机波形再现是一种正在探索的方法。依据CARMA模型求得的控制量往往会出现高频大幅值的振荡 ,采用数字滤波方法可以抑制控制量的这种振荡。
An automotive road simulated testing machine controlled by CARMA model is now being researched. The control values, which are calculated by the CARMA model, indicate as a vibration with large amplitude and high frequencies. It is shown that this vibration can be weakened by a digital filter.
