Fuzzy type-2 sliding mode control of matrix converter using indirect space vector modulation

Abstract

Employing sliding mode controller in matrix converters presents advantages such as easy on-line implementation, quick and reliable choice of the correct switching combinations and ensuring that the system tracks their references. The main drawback of the sliding mode controller is chattering phenomenon which affects the performance of the controller by injecting high frequency variation in controller object variables. To solve chattering problem, this paper proposes a new input current control method for matrix converter using interval fuzzy type-2 integrated with sliding mode control. Theoretical analysis and simulation results demonstrate the authenticity of the proposed input current control method of matrix converter in various conditions.
