摘要： A proportional integrator for control of a motor drive arranged to be connected in parallel with one or more other motor drives to drive a common load. The proportional integrator includes means to receive an input command signal and to compare with a local measured signal from the motor drive and to output a local control signal for that motor drive. Also includes are a global input signal indicative of the behaviour of the one or more other motor drives, the global input signal being incorporated into the proportional integral function with the input command signal and the local measured signal to provide the local control signal.

摘要： A system and method includes parallel power converters, at least one current sensor, and a first feedback control circuit. A first power converter is configured to convert a first input power to a first output power, and is controlled using pulse width modulation having a first switching period. One or more second power converters are connected in parallel with the first power converter and configured to convert a second input power to a second output power. The first output power and the second output power are provided to a load. The at least one current sensor is positioned to sense first output current of the first output power, and the first feedback control circuit is configured to calculate a first metric based on the first sensed current at each of a plurality of first edges of each half switching period of the first switching period, and at intermediate points between each of the plurality of first edges. The first feedback control circuit is configured to adjust the first switching period based upon the first metric.

摘要： The present disclosure provides a system and method that provides active damping at the input of a motor drive system without the need for the hardware used in conventional and RC damping circuits. According to the disclosure a virtual damping network is realised at the input of the motor drive system based on modification of field-oriented control, FOC. More specifically, a control algorithm creates a virtual damping impedance at the motor drive input by applying a damping algorithm to both q and d components of the motor current.
