The invention discloses an active suspension control strategy based on a fuzzy theory, and the strategy comprises the steps: building a road surface excitation model based on a white noise method, building a road surface time domain response model which reflects the unevenness of a road surface, building a suspension model of seven degrees of freedom of a whole vehicle, and employing the fuzzy theory according to a PID controller. An active suspension fuzzy control-PID controller is established, an actuator model of an active suspension system is established, and the active suspension control strategy based on the fuzzy theory provides an accurate model actuator for the control strategy. Off-line simulation can be carried out, and the influence of factors of other people in a real vehicle experiment is avoided.

    本发明公开一种基于模糊理论的主动悬架控制策略,包括基于白噪声法建立路面激励模型,建立体现路面不平度的路面时域响应模型、建立整车七个自由度的悬架模型、根据PID控制器,运用模糊理论,建立主动悬架模糊控制‑PID控制器以及建立主动悬架系统的作动器模型,该种基于模糊理论的主动悬架控制策略,为控制策略提供准确的模型执行器。能够进行离线的仿真,避免了实车实验的其他人为因素的影响。
