摘要： 基于车辆动力系统模型，设计了针对车辆平顺性的4自由度车辆主动悬架系统半车模型。针对提高车辆平顺性设计了模糊控制规则库，并将模糊控制逻辑结合到PID控制当中，设计了主动悬架系统的模糊PID控制器。通过MATLAB / Simulink仿真分析了基于模糊PID控制器的主动悬架与被动悬架的性能。仿真结果表明:设计的模糊PID控制器，能显著降低车身加速度和俯仰角，提高主动悬架的平顺性。

Abstract: A fuzzy-PID controller was developed to the active suspension system for the ride comfort enhancement of a half-vehicle model of a four degree-of-freedom based in vehicle dynamical model. A fuzzy-PID controller was developed by incorporating the fuzzy logic control mechanism into the PID structure focused on the passenger’s ride comfort performance.The performance of the proposed controller has been verified by comparing it with passive control method in MATLAB/Simulink. The simulation results indicate that the developed fuzzy-PID controller enhances the ride comfort performance of the vehicle active suspension system by reducing the body acceleration and pitch angle significantly.
