Summary: | This paper addresses a dissipative-based controller design approach for a single phase DC to AC converter with output LC filter. We derive the state space model of the inverter by considering load as an exogenous disturbance input modeled as current source in parallel with an uncertain linear load. Based on norm-bounded linear differential inclusion (NLDI) notation, D-stability, and linear matrix inequality (LMI) techniques, sufficient conditions are derived to design the robust state feedback aiming for performance improvement. Also, according to the internal model principle, a resonant controller is used to remove the steady state error. Simulation results show the efficiency of proposed method. Furthermore the output dynamic performance of the inverter strongly satisfies the IEC62040-3 and IEEE 1547 standards. |
