The invention discloses a fuzzy self-adaptive sampling controller of an active suspension system, a structure and a design method. The method comprises the steps of collecting the vertical displacement and vertical vibration rate of a vehicle body, the vertical displacement and vertical vibration rate of wheels, and the current of an electromagnetic driver, carrying out processing through a time judgment module and a data processing module, obtaining self-adaptive parameters by using a fuzzy self-adaptive law module, processing the self-adaptive parameters into optimized self-adaptive parameters through the data processing module, adjusting current through designed voltage signals according to the optimized self-adaptive parameters, and returning potential energy generated by counter electromotive force to an automobile suspension system. Therefore, the active automobile suspension system can effectively control the automobile suspension system according to the sampling data, and the automobile suspension system can reach a stable state by controlling the input current of the electromagnetic driver.
