Title:
VIRTUAL INERTIA-BASED CHARGE/DISCHARGE CONTROL METHOD FOR ELECTRIC VEHICLE
Document Type and Number:
WIPO Patent Application WO/2020/192006
Kind Code:
A1
Abstract:
A virtual inertia-based charge/discharge control method for an electric vehicle, comprising: obtaining an input signal; obtaining the difference between the input signal and a reference value and outputting the difference; performing proportional integral (PI) processing on the difference by means of a PI controller, and introducing virtual inertia by means of a virtual inertia compensation function connected in parallel to the PI controller for compensation; and outputting a modulation signal. The introduction of a virtual inertia compensation function into an outer loop of conventional control increases the system inertia; the virtual inertia-based control provides high damping and large inertia, causes direct current bus voltage oscillation in a virtual inertia charge/discharge mode to gradually attenuate until it is stable, and has stronger damping capability than a conventional control method.
