Parameters of an inner loop proportional integral (PI) current control based on "Reduced-order Structure-preserving Model for Parallel-connected Three-phase Grid-tied Inverters."

Arguments

γd_ic: d-axis integrator state of the PI current controller,
γq_ic: q-axis integrator state of the PI current controller
  • n_states::Int: (Do not modify.) CurrentControl has 2 states
