| description | A current reference generator to control a brushless motor in a motor control system is provided. The current reference generator includes a locate peak torque module that determines a maximum possible torque and a direct axis current that corresponds to the maximum possible torque based on motor parameters, a maximum voltage, a motor velocity of the brushless motor, and a sign of a torque command. A limit torque command module limits the torque command to the maximum possible torque. A locate minimum current module determines a value of the direct axis current that results in a minimum motor current. A solve current reference module generates a reference vector that satisfies the torque command as limited by the direct axis current that corresponds to the maximum possible torque and the direct axis current that results in the minimum motor current. |
