Abstract
Various kinds of fuzzy logic controllers (FLC) have been well investigated and widely used nowadays in industry, although there are rather few literatures being useful investigated the tuning of fuzzy controllers [1-4], the tuning strategy of fuzzy controllers has not been well established. In this paper the 5 parameters of fuzzy logic controllers are full investigated, and defined: (1) the value L for inputs and outputs of FLC is the absolute value of the reference signalr(kt). (2) the output scaling coefficientsG U of the FLC is β times of the max of among the parametersK P , K I , K D of the conventional PID controllers. (3) Based on the above two conditions, we established the relationship between the inputs scaling coefficients G P , G I , G D of the FLC and the parametersK P , K I , K D of the conventional PID controllers. Also we proposed the convertibility between the parameters of the FLC and the conventional PID controllers. The simulation research results show that the control performance of the FLC is close to that of the conventional PID controllers.
