and multiple parameters in existing PI controller identification methods for rotor-side converters (RSC) of doubly-fed induction generators (DFIG)
a hierarchical identification framework combining an improved black hole algorithm (IBHA) with the RT-LAB hardware-in-the-loop (HIL) co-simulation platform is proposed. Firstly
based on the RSC control dynamics
the operational characteristic data of the actual controller of DFIG is collected by the RT-LAB HIL co-simulation platform. Secondly
a trajectory sensitivity analysis is performed to quantify the dynamic response characteristics of each parameter
followed by the selection of optimal observables and a rigorous identifiability assessment based on persistent excitation criteria. Thirdly
a stepwise identification strategy is established based on the RT-LAB measured data and IBHA. Finally
based on the HIL test data
the identification results of several algorithms are compared and analyzed
which verifies the effectiveness of the proposed method.
