Abstract

The paper concentrates on H∞ control problem of switched IT2 fuzzy nonlinear systems with multiple time delays and disturbance. The problem exists extensively in hybrid grid-connected generation converter system, which can be felicitously described through switched interval type-2 (IT2) fuzzy model for bifurcation behavior, electromagnetic interference. The application of IT2 fuzzy switched descriptor in hybrid grid-connected generation is proposed for the first time avoiding bifurcation behavior effectively and successfully coordinates the individual components of the hybrid grid-connected generation system leading to operating in a dynamically stable way subordinating to the given patterns. To ensure the system stable subjecting to disturbance, methods of LMI and free-weighting matrices are employed to design the controller. Availability and validity are verified through a numerical simulation.
