First, the properties and vulnerabilities of the existing TA methods are analyzed. A model for TA on ANIFIS with Takagi-Sugeno type is established. Then, the attribute functions, i.e. membership and nonmembership functions, and the inference rules of the system variables are devised with computational relations between layers of input and output and a synthesized computational expression of system outputs ascertained. Subsequently, an analysis of global approximation property of the model is performed with a lear
