Optimum selection of state feedback variables PWM inverters control

摘要: Different control schemes for voltage source inverter interfacing are presented and compared. state feedback approaches investigated, therein identifying a generalized optimum variable selection criterion that is appropriate to the of systems using an LCL passive filter. A standard synchronous proportional plus integrator (PI) controller added into outer loop achieve zero steady error. (P) inner used provide fast dynamic compensation. Finally, system harmonic impedance expressions derived study effects supply distortion on performance. The has been verified through similarities between different waveforms experimental implementation.
