how to combine PID controller with Fuzzy logic controller to control DC Motor?

PID controller have a good system to control for DC motor... i want to combine Fuzzy logic and PID controller to get a better result than PID controller only.

A common approach is fuzzy gain scheduling for PID controllers, which is presented in this paper:

Zhen-Yu Zhao; Tomizuka, M.; Isaka, S., "Fuzzy gain scheduling of PID controllers," in Systems, Man and Cybernetics, IEEE Transactions on , vol.23, no.5, pp.1392-1398, Sep/Oct 1993

Implementation of this method, using Simulink and Fuzzy Logic Toolbox is available to download, in MATLAB File Exchange, in the following link:
