Modulated Model-free Predictive Voltage Control for LC-filtered Inverter Based on Luenberger Observer
The conventional modulated model predictive voltage control usually has difficulty in maintaining the stability and accuracy of the output voltage when facing parameter uncertainty and various disturbances in the LC-filtered inverter system
especially in the case of parameter mismatch
the control performance declines significantly. To address this issue
this paper proposes a Luenberger observer based modulated model-free predictive voltage control (LO-M
2
FPVC) strategy. This strategy mitigates the impact of system disturbances on the calculation of modulated prediction
ensuring the robustness of the inverter output voltage control. First
a parameter-free Luenberger observer is developed for the inverter to accurately identify parameter changes inside the LC-filtered inverter and other external disturbances. The observed disturbance information is then integrated into the calculation of modulated prediction
eliminating the influence of disturbances on the duration calculation of each voltage vector in modulated prediction. Finally
an experimental platform for the LC-filtered inverter is constructed to verify the effectiveness of the proposed LO-M
