Abstract

Due to the complexity of the brushless doubly-fed machine model, its winding parameters are difficult to identify. Based on the structural characteristics of the brushless doubly-fed machine, this paper proposes an integrated coupling parameter identification method. This method derives the relationship between voltage and current between windings based on the control model, measures the electrical quantity of the brushless doubly-fed machine in steady state, and calculates the integrated coupling parameters at the control winding side. This method bypasses the problem of direct identification of motor winding parameters, and can be directly used in controller design. Finally, the experimental verification is carried out on the 30 kW brushless doubly-fed machine experimental platform, and the experimental results show that the proposed method is feasible and effective.
