Fuzzy controller could approach to any linear or nonlinear functions; meanwhile, it is also an effective way to construct nonlinear function. The fuzzy controller in this paper adopts the same structure to the literature[8, 9]. It has two input variable and one output variable. The two input variables are the output of P immune controller u(k) and its variation Δu(k) apart, output variable is the suppressing-quantity of Ts cell f (u(k),Δu(k))
