Abstract

Embodiments of the present disclosure relate to methods, systems and apparatus for adjusting current and / or torque commands used to control operation of an asynchronous machine based on rotor flux of the asynchronous machine.

Description

technical field [0001] The technical field relates generally to techniques for controlling the operation of polyphase systems, and more particularly to methods, systems, and apparatus for adjusting current and / or torque commands used to control the operation of asynchronous electric machines. Background technique [0002] Electrical machines are used in a wide variety of applications. For example, a hybrid / electric vehicle (HEV) typically includes an electric traction drive system that includes an alternating current (AC) electric machine driven by a power converter with a direct current (DC) power source, such as a battery. The motor windings of the AC motor may be coupled to the inverter sub-module of the power inverter module. Each inverter sub-module includes a pair of switches that switch in a complementary manner to perform a fast switching function to convert DC power to AC power. This AC power drives the AC electric motor, which in turn drives the shaft of the HEV'...
