【摘要】 以两自由度汽车1/4模型作为研究基础,采用模糊数—模糊控制(FFC)策略设计了半主动悬架控制系统,并用MATLAB软件进行了性能仿真。在输入一定激励信号的情况下,把模糊控制半主动悬架与被动悬架及PID控制半主动悬架的工作情况进行了比较。仿真结果表明,模糊控制技术(FCT)能更好地实现控制效果,显著地减小车辆振动,提高车辆行驶的平顺性。更多还原

【Abstract】 In this paper,the semi-active suspension control system is designed by fuzzy figure-fuzzy control (FFC) tactic,in which 1/4 vehicle model is used as the basis of research and MATLAB software is used to simulate the performance. Under the input of certain actuating signals,FFC semi-active suspension is compared with non-active suspension and PID control semi-active suspension. The simulation results show that the fuzzy control (FCT) could obtain the better control effect. Furthermore,FCT can clearly reduce the vehicle′s vibration and improve the vehicle′s ride comfort characteristics.更多还原
