Lévy Distribution Meta-Heuristic Fuzzy-Based Optimization Algorithm for Optimal Framework Design of Type-2 Fuzzy Controller: Subject to Perturbations ^†

New metaheuristic algorithms have recently been created based on Lévy Flight (LF), drawing inspiration from biological and natural events. Many researchers have adopted this nature-inspired approach to algorithm creation in order to solve optimization challenges. These algorithms have been tested against standard algorithms and have proven to be superior in a variety of complicated problems. One of the most powerful aspects of Cuckoo Search (CS) is the use of Lévy steps to generate fresh possibilities. This approach modifies possible solutions by causing a large number of changes and a few major transitions. As a consequence of this, CS will be able to greatly improve its research skills while also increasing the connection between exploration and exploitation. In this research, the Interval Type-2 Fuzzy Logic Controller (IT2FLC) is introduced to the typical Cuckoo Search Optimization (CSO) algorithm to ascertain the optimal membership function (MF) parameters of Interval Type-2 Fuzzy Logic Systems (IT2FLSs). The investigation considers two types of MFs: triangle and trapezium. Whenever disturbances are used to execute each control issue, the CSO algorithm′s performance and efficacy boost dramatically. Two standard control problems are used to evaluate the suggested method: one is a tank level controller and the other is an inverted pendulum controller. The primary purpose is to demonstrate the effectiveness of the CSO algorithm in locating suitable fuzzy controllers for nonlinear plants. All control problems consider two forms of disturbance. The CSO algorithm produces good results in the field of fuzzy logic controllers (FLCs), according to the findings.
