The invention discloses a fuzzy adaptive compensation control method in performer time lag and failure; the method comprises the following steps: building an industrial system model with a performer failure, wherein the industrial system model comprises time lag performer failure fault description functions; building a virtual controller and virtual controller satisfying adaptive rules according to preset transient performance parameters, thus controlling the industrial system model tracking errors when the time lag performer failure faults happen. The method can ensure the system transient tracking performance stability when the performer simultaneously has time lag and failure. 本发明公开了种执行器时滞和失效时的模糊自适应补偿控制方法，该方法包括：建立带执行器失效的工业系统模型；该工业系统模型包含时滞执行器失效故障的描述函数；再根据预设的暂态性能参数，建立虚拟控制器和所述虚拟控制器需满足的自适应法则，以使得在时滞执行器失效故障时，控制工业系统模型的跟踪误差。采用本发明实施例，能在执行器同时存在时滞和失效时，保证系统瞬态跟踪性能稳定性。
