摘要: A method of controlling a motor is provided. The method may determine a speed of the motor, and engage a soft chopping routine on a first switch and a second switch of each phase if the motor speed is relatively low. The first switch may be driven by a first pulse width modulated PWM signal and the second switch being driven by a second PWM signal. The first and second PWM signals may be alternatingly configured such that at least one of the first switch and the second switch is closed at any point during the distributed soft chopping routine and both the first switch and the second switch are never simultaneously open.

摘要: A control system for a switched reluctance (SR) machine is provided. The control system may include a converter circuit that is operatively coupled to the SR machine, and a controller in communication with the converter circuit. The controller may be configured to execute two or more processes in parallel, wherein the processes include generating a torque command based on one or more of bus voltage, machine current, rotor speed and rotor position, determining a first set of current control parameters based on the torque command and the rotor speed, determining a second set of current control parameters based on one or more of the torque command, the rotor speed and the rotor position, selecting one of the first and second sets of current control parameters based on the rotor speed, and operating the gates according to the selected set of current control parameters.

摘要: A method of controlling a generator (110) of an electric drive (104) associated with an engine (102) is provided. The method may determine an operational state of the electric drive (104) based on a speed of the engine (102), and selectively engage one of a map-lookup control scheme (150) and a fixed-theta off control scheme (152) for operating the generator (110) based on the operational state of the electric drive (104).
