Adaptive Interval Type 2 Fuzzy Fractional Order Sliding Mode Control for Permanent Magnet Synchronous Generators

This paper proposes a design of adaptive interval type 2 fuzzy logic robust nonlinear controller using the fractional sliding mode approach. The control method is used on the permanent magnet synchronous generator for a variable speed wind conversion system. To attenuate the chattering effect, adaptive interval types 2 fuzzy systems are used to substitute the sliding discontinuous signals. The control scheme is achieved from the stability study of lyapunov’s approach. To compare the tracking performance and system robustness of the proposed fractional control method to the conventional sliding approach, simulation tests via Matlab/Simulink environment, are carried out under external disturbances and parameter variations.
