摘要： A control sub-system for controlling an electric machine is presented. The control sub-system includes a phase shift control unit to receive an electric signal indicative of an angular position of a rotor. The phase shift control unit generates a phase shifted electric signal by applying a phase shift to the electric signal. The magnitude of the phase shift is determined based on a speed control signal. The phase shift control unit is configured to generate a phase command signal based on the phase shifted electric signal. The control sub-system also includes a switching unit to control a supply of a phase current to one or more phase windings the electric machine based on the phase command signal such that the rotor is operated at a predetermined rotational speed.

摘要： Power delivery systems and methods described herein conductively couple several input lines with a cable that conducts a multi-phase electric current. The input lines separately conduct different phases of the electric current. Output lines are conductively coupled with plural machines, and separately conduct the different phases of the electric current. Plural switching devices are conductively coupled with the input lines and with the output lines, and are used to control the switching devices in order to conduct the different phases of the electric current to the machines. A first set of the switching devices is closed to separately conduct the different phases of the electric current to a first machine of the machines. A different, second set of the switching devices is separately closed to separately conduct the different phases of the electric current to a different, second machine of the machines.

摘要： A method of controlling torque ripple in a switched reluctance motor (SRM) includes splitting each phase winding of the SRM into an AC winding and a DC winding. The AC winding of each phase winding is excited with symmetrically displaced sinusoidal currents that may be projected into a reference frame that moves synchronously with the SRM rotor.
