Speed Control of a dc Motor using a New Fuzzy Controller

Abstract

The development of a PC-based fuzzy controller for controlling the speed of a dc motor is considered. It is shown that the proposed controller results in a reduced chattering around the set point as compared to a basic fuzzy controller. The performance of the fuzzy controller and its capability of optimizing the parameters like maximum overshoot and rise time are described. The results obtained on a practical dc motor control system are presented.

Indexing terms:

• dc motor
• Fuzzy logic
• speed control
