The design of nonlinear servo system using fuzzy method

In this paper, the design of the nonlinear fuzzy servo system will be discussed. The idea behind of this control method is to divide the operating region of nonlinear servo system into small areas, and treated as a collection of local linear servo systems. The control rule of each local linear servo systems has been calculated using Davison-Smith Method. Fuzzy method has been applied to each local linear servo system and combines it as new control rule. The Lyapunov stability theory is used to develop the bounded condition for the proposed system. The simulation of the inverted pendulum system has been done to illustrate the effectiveness of the proposed method. The result shows that the proposed method can stabilize the system.
