Abstract
Fuzzy logic in control systems is becoming increasingly popular as a method of handling non-linear control problems. The design of fuzzy logic controllers (FLC) is often undertaken using a trial and error approach; an important generalisation is the addition of a self-organising structure that enables to achieve a better performance of the controlled process, by on-line improvement of the fuzzy control algorithm. Even if the topic has been extensively studied, in the area of the electrical drives there is still lack of implementation examples. In this work a self organising controller (SOC) is applied to the speed control of a DC motor, to test the increased robustness of the drive against the parameters on-line variations. Details on the SOC parameters choice and design are also included in the paper.
