Fuzzy Fractional Derivative: A New Definition

2017
In this paper, a new definition of fuzzy fractional derivative is presented. The definition does not have the drawbacks of the previous definitions of fuzzy fractional derivatives. This definition does not necessitate that the diameter of the fuzzy function be monotonic, and it does not refer to derivative of order greater than the one that is ...

Fractional Derivatives with Fuzzy Exponent

2009
Fractional derivatives with fuzzy exponent defined with the help of new type of fuzzy numbers are introduced. New model of fuzzy numbers, called ordered fuzzy numbers (OFN), invented in 2003 by the author and his coworkers, is also shortly presented.

Design of fuzzy proportional plus fractional-order integral-derivative controller

2016 IEEE International Conference on Automatic Control and Intelligent Systems (I2CACIS), 2016
Fractional-order PID (FOPID) controller has been focused lately and has become a popular controller which is an extension to the conventional PID controller. However, the controller introduced more parameters that need to be tuned. The incorporation of fuzzy rules in the tuning procedures can basically simplify the problem but it has been proven that ...
