Analysis on Advancement of Hybrid Fuzzy Sliding Mode Controllers for Nonlinear Systems
Chattering phenomena is the major problem affecting sliding mode control
(SMC). Also, finding a suitable structure and appropriate parameters values of
fuzzy logic system (FLS) is a complex and difficult task. In addition, the
stability of a general FLS is difficult to guarantee. Many types of
combinations between FLS and SMC have been used to form an intelligent and
robust controller that deviates from the limitations of each constituent and
benefit from the advantages of each constituent. In this study, a survey of
recent developments on the Hybridization of FLS (type-1) and SMC is presented.
In addition, the differences between using the SMC in FLC or using FLC in SMC
as well as their limitation and advantages are highlighted. It is found that
the majority of the combinations made are intended to approximate the nonlinear
sliding surface within the boundary layer. Limitations of the previous
approaches and future research directions are pointed out. For novice
researchers, this survey can serve as a foundation for their work while for
expert researchers this review can serve as a benchmark for further advancement
and exploration of other hybridization methods
