Inverter control method and system, controller and storage medium

The invention discloses an inverter control method and system, a controller and a storage medium, and relates to the technical field of motor control, and the method comprises the steps: obtaining at least one open-phase position of an inverter when the inverter has an open-phase fault; determining a phase limit range of a current vector output by the inverter according to the at least one open-phase position; within the phase limiting range, target current vectors corresponding to a plurality of preset motor rotor positions under the set motor torque are determined; and controlling the inverter to work according to all the target current vectors. According to the method and the device, the inverter is controlled to output different current vectors within a phase limiting range at different preset motor rotor positions on software, so that phase-lacking operation of the inverter is realized, redundant topology does not need to be added in the inverter, a control strategy of the inverter does not need to be ch
