%X The structure of a novel fuzzy PID controller, which is of one - input with three rules, is introduced and its nonlinear characters are analyzed in the paper. Based on this, the nonlinear gain properties of the one - input fuzzy PID controller are analyzed by a linearization method in such a way that the nonlinear curve is piecewise linearized to approximate the nonlinear characteristics. By this approach the nonlinear gain is quantified and simplified, and stability is analyzed by the circle criterion. The computer simulation shows that the proposed method is effective.
