%X 为提高车辆行驶舒适性和减小轮胎对路面动载荷，建立二自由度天棚阻尼控制的半主动汽车悬架模型，将分数阶微积分理论应用到天棚阻尼控制的半主动汽车悬架上，采用Oustaloup数字滤波器模拟分数阶微积分，进而通过遗传算法寻找出分数阶天棚控制的最优参数。最后，建立分数阶天棚阻尼悬架系统的仿真模型，并对其进行时频域仿真分析。仿真结果表明：分数阶天棚阻尼半主动悬架在保持整数阶控制性能的前提下，在各个方面均有一定的提高和改善。<br>In order to improve vehicle ride comfort performance and reduce the tire dynamic load, the 2-DOF dynamic model of semi-active suspension system with sky-hook damping was established. Then the fractional calculus theory was applied to the semi-active suspension, and an Oustaloup digital filter algorithm was used to simulate the fractional calculus. Then the optimal parameters of the fractional order sky-hook damping controller were solved by using genetic algorithm. Finally, the simulation model of semi-active suspension with fractional order sky-hook damping control was built and analyzed in time and frequency domain. The simulation results indicate that the semi-active suspension of fractional order sky-hook damping controller can suppress resonance effectively
