For delay problem brought by asymmetric drop of traditional control strategy based on double dq and PI regulator, a control strategy based on PR regulator was proposed, namely use closed-loop power to get positive sequence current quantitative required by rotor-side converter, and calculate negative sequence current quantitative by inhibiting the second harmonic of electromagnetic torque. Matlab/Simulink simulation results show that the control strategy based on PR regulator solves delay problem effectively, and has better control performance than control strategy based on double dq and PI regulator.
