Study of Improved Repetitive Control Inverter Based on Fuzzy Adaptive
In this paper,the single-phase full-bridge inverter is taken as the research object,and fuzzy control technol-ogy is introduced on the basis of the overall double-closed-loop control strategy,replacing the traditional PI controller with the fuzzy adaptive PI controller with strong dynamic adjustment capability,which strengthens the system's ability of resisting parameter variations and various nonlinear uncertainty perturbations,and improves the dynamic perfor-mance of the system.At the same time,the harmonic content of the output voltage is reduced through the repetition control which improves the quality of the output voltage and improves the steady state characteristics of the system.Finally,the proposed strategy is verified by MATLAB/Simulink simulation,which confirms that the method still has a good control effect when facing different disturbances.
