摘要： The invention relates to an electronically commutated electric motor with a stator and a rotor, which is designed as a permanent magnet rotor in particular. The electric motor also has a control unit which is connected to the stator. The control unit is designed to generate control signals for energizing the stator coils of the stator in order to generate a rotational magnetic field. The electric motor is designed to at least partly compensate for a torque ripple of a torque generated by the rotor. According to the invention, the electric motor has a rotor position sensor and a current sensor. The current sensor is designed to detect currents flowing in the stator coils and to generate a current signal which represents the currents. The control unit preferably has a processing unit which is designed to ascertain harmonics of the electromotive force dependent on the current signal, a voltage applied to the stator coils, and a rotor position signal generated by the rotor position sensor and to generate a control signal which compensates for the effect of the harmonics. The control unit, in particular the processing unit, is designed to superimpose the compensating control signal with the control signal so as to completely or at least partly compensate for the effect of the harmonics and thus the torque ripple.

摘要： A system including a motor loss reducing controller system utilizing input band-shifting, an integral control architecture and inverse band-shifting is disclosed. The motor loss reducing controller system may provide correction of harmonic currents flowing to a PM motor from a motor controller. The compensation is added to the PWM voltage command signals. Within a compensator, d-axis and q-axis current feedback signals are frequency shifted down by n times the fundamental frequency. This converts the initial motor stationary harmonic currents into DC values. The frequency shifting is completed by multiplying the feedback signal by sine and cosine carrier signals of the shifted frequency. An integral controller may cancel any component of error at a desired DC value. An inverse frequency-shift transformation is applied to the output of the I controller in order to shift the command output signal back to the original reference frame.

摘要： A hybrid-electric vehicle and method of controlling a hybrid-vehicle is provided. The vehicle includes a traction battery, at least one electric-machine, and a controller. The controller is configured to alter a voltage between the battery and the electric-machine based on a measured voltage of the battery or the high voltage bus. In response to an indication that the measured voltage is faulty during a drive cycle, the controller instead alters the voltage between the battery and the electric machine based on a substituted battery voltage signal such that the electric-machine remains operable for the drive cycle.
