Title:
CONTROL DEVICE AND METHOD FOR CONTROLLING AN ELECTRIC MACHINE
Document Type and Number:
WIPO Patent Application WO/2013/000654
Kind Code:
A3
Abstract:
A control device (11) for controlling an electric machine (22) with ks windings on a stator and kr windings on a rotor, wherein ks+ kr = n and wherein either one of ks and kr may be zero, comprises an input via (12) which control commands are capable of being received in real-time and an output (14) via which control commands to a driver (21) of the electric machine are capable of being output in real-time; machine modeling means (15) provided for modeling the behavior of the electric machine in real-time; and decision means (16) operatively connected to the input, the output, and the machine modeling means and, in real-time, provided for (i) determining the control commands to be output to the driver of the electric machine based on input control commands and results from the modeling of the behavior of the electric machine, and (ii) outputting the determined control commands at the output. -The machine modeling means is provided for modeling the behavior of the electrical machine through at least one functional mapping suited for correlating sets of values of electrical and mechanical quantities and/or sets of values of their total or partial derivatives and/or integral functions with one another, wherein the electrical and mechanical quantities comprise winding currents, winding voltages, magnetic fluxes, mechanical displacements, and/or electromagnetic torques or forces; and the functional mapping comprised of at least one algorithm and/or mathematical equation based on at least one state function associated with the electromagnetic field inside the electrical machine and/or based on at least one partial derivative of said state function.
