Abstract
The present invention provides an electro-mechanical energy exchange system with a variable speed synchronous reluctance motor-generator having an all-metal rotor. A bi-directional AC-to-DC electric power converter interconnects the motor-generator with a DC bus. First and second hybrid controllers provide current regulation for the motor-generator and voltage regulation for the DC bus. Use of both feedback and feedforward control elements provides a controller particularly suited for operating high speed devices.
Claims9
A synchronous reluctance machine and control system comprising:
- a bi-directional AC-to-DC electric power converter electrically interconnecting and bi-directionally exchanging electric power between a synchronous reluctance motor-generator and a DC bus wherein said power exchange is controlled by a plurality of current controllers operably coupled to said converter wherein at least one of said controllers is a feedforward controller.
An energy conversion system comprising:
- a bi-directional AC-to-DC electric power converter electrically interconnecting and bi-directionally exchanging electric power between a synchronous reluctance motor-generator having an all-metal rotor and a DC bus, the power exchange being controlled by a plurality of current controllers operably coupled to the converter wherein a first controller is a feedforward controller, a second controller is a feedback controller and a control voltage output of at least one controller is a function of peak current.
