This paper presents a new approach to stabilizing a Takagi–Sugeno (TS) fuzzy model. A new controller design called proportional parallel distributed compensation (PPDC) is proposed. Different from other works, PPDC parameters are proportioned, which result in dramatic reduction in control parameters. In our new design, based on the Lyapunov stability analysis, the solution of finding the common positive definite matrix P is simplified and proportional coefficients design can be separated from feedback matrix parameters. Numerical simulation results show that the PPDC's performance is superior to that of PDC. This new approach has promising potential in practical applications of fuzzy systems. © 2001 John Wiley & Sons, Inc.
