Self-evolving Multilayer Type-2 Fuzzy Controller Design For Time-Varying Delay Systems

This study presents a design of the multilayer type-2 fuzzy controller (MT2FC) to control the time-varying delay systems. By using the proposed multilayer structure, the number of fuzzy rules can be reduced while ensuring good coverage of input states. The self-evolving algorithm is used to automatically obtain the optimal network structure. The network parameters are updated online using the gradient descent method. Finally, the performance of the proposed control method is illustrated by numerical simulations of the time-varying delay systems.
