为了减小车辆悬挂系统的振动 ,采用半主动悬挂系统作为对象 ,并建立了其CARMA模型 ,提出了自适应控制中的两种算法 :最小方差自校正控制算法和极点配置自校正控制算法 .前者可使系统输出的方差最小 ,而后者可使系统的动态特性达到预期的目的 .仿真结果表明 ,车体垂直方向的加速度大大减小 ,减振的目的也已达到 .这两种算法都能减小悬挂系统中的振动 ,具有一定的实用性 In order to reduce the vibration of the vehicle suspension system, the semi-active suspension system is used as object, and its CARMA model is established. Two algorithms in adaptive control are proposed: minimum variance self-tuning control algorithm and pole configuration self-tuning control algorithm. Which can make the output of the system minimize the variance and the latter can make the dynamic characteristics of the system achieve the desired purpose.The simulation results show that the acceleration of the vehicle body in the vertical direction is greatly reduced and the purpose of damping is achieved, Small suspension system in the vibration, with some practicality
