Adaptive fuzzy logic controllers for dc drives : a survey of the state of the art

Abstract EN

Fuzzy Logic Control (FLC) has gained a great demand in process control applications.

Fuzzy Logic (FL) technology enables the use of engineering experience and experimental results in designing an expert system capable of handling uncertain or fuzzy quantities.

This paper presents a comprehensive review of FLC in the field of Direct Current (DC) motor drive systems.

Firstly, the principles of fuzzy logic theory will be briefly presented.

Secondly, the employment of the FL techniques in a control system will be outlined.

The concept of FLC can be extended for application to different DC motor drives such as : series, separately, shunt and permanent magnet DC motor.

The limitations of FLC when applied to DC motor drives have been widely reported in the literature.

This article also cites these limitations as well as the advancements in solving them through, for example, the genetic algorithms and the neural networks techniques.
