Abstract

This paper presents an introduction to fuzzy logic and its application in speed control of dc motor. Lotfi Zadeh, a professor at the university of California at Berkley who conceived the concept of fuzzy logic, and presented not as a control methodology ,but as a way of processing the data by allowing partial set membership rather than crisp set membership or non-membership.This approach to set theory was not applied to control system until the 70’s due to insufficient small computer capability prior to that time. Prof zadeh reasoned that people do not require precise, numerical information input, and yet they are capable of highly adaptive control. If feedback controllers could be programmed to accept noisy, imprecise input, they would be much more effective and perhaps easier to implement.
