The need for renewable energy sources is increasing while the use of non-environmentally
energy sources is decreasing day by day. At this point, solar energy which is a great natural …

Fractional order PID controller was received attentions in control problems for it had 2
freedom adjustable parameters. Practices had proved that better results could be obtained …

In this study, an interval type‐2 fuzzy proportional–integral–derivative (IT2FPID) controller is
designed to be used in the air flow regulation of polymer electrolyte membrane fuel cell …

Neuro-fuzzy systems have been proved to be an efficient tool for modelling real life systems.
They are precise and have ability to generalise knowledge from presented data. Neuro …

In this paper, a general type-2 fuzzy controller is proposed. The proposed general type-2
fuzzy controller is based on α-plane representation, which converts the centroid of general …

The present paper aims to analyze the stability of dynamic Interval Type‐2 fuzzy control
systems (IT2 FCSs) with adjustable parameters by investigating the existence of limit cycles …

Fuzzy logic has always been one of the key research areas in the field of computer science
as it helps in dealing with the real world vagueness and uncertainty. In recent years, a …

This paper deals with the concept and application of general three-dimensional (3-D) type-2
fuzzy logic systems in the polar frame (G3DT2FLS). 1 We focused on the automatic …
