摘　　要：针对生物流化床污水处理系统的非线性、时滞、时变等问题,提出采用T-S模糊控制方法,将复杂的非线性系统模糊化为局部线性模型,并引入积分环节,降低T-S模糊控制器维数,简化规则.最后,通过实验进行理论验证.实验结果表明,该方法可行且有效.In order to overcome the shortcomings of the nonlinear,time-delay and time-varying problems in sewage disposal system based on biological fluidized bed（BFB）,T-S model fuzzy control system is proposed and the nonlinear system has been fuzzified into local linera model.Then reduce the dimension of fuzzy controller and simplify the rules by introducing an integral unit.Finally,the method is verified by experiments.Experimental results show that the method is feasible and effective.
