In this paper, a self-tuning fuzzy controller with a smart and easy st
ructure is presented. The tuning schemes allow us to tune the scaling
factors by only seven rules. The aim of a controller is to obtain a sa
tisfactory performance, such as the rise time, the overshoot, the stea
dy-state error for the step response. Simulation results of a third or
der system with time-delay show a better performance and ability of cu
rbing the effect of load disturbance on the control process. (C) 1998
