Method And System For Controlling An Induction Machine

View page
US Patent:
6590361, Jul 8, 2003
Filed:
Jul 19, 2001
Appl. No.:
09/909356
Inventors:
James E. Walters - Carmel IN
Fani S. Gunawan - Westfield IN
Gerald Thomas Fattic - Fishers IN
Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
H02P 142
US Classification:
318727, 318804, 318805, 318806, 318807, 318808, 318809, 318810, 318811
Abstract:
Method and system for controlling an induction machine are provided. The method allows to sense rotor position of the induction machine using a relatively low-resolution rotor position sensor configured to supply a stream of pulses indicative of angular increments as the rotor position changes. A memory device is used for storing a synchronous angle boost function. The method further allows to retrieve from the memory device at least one function parameter for providing a synchronous angle boost during a start up mode of operation of the induction machine. Upon sensing a predetermined number of pulses from the rotor position sensor, the method allows to switch from the start up mode of operation to a normal mode of operation, wherein the boost provided to the synchronous angle is discontinued upon switching to the normal mode of operation.

Method And System For Controlling A Permanent Magnet Machine During Fault Conditions

View page
US Patent:
6741060, May 25, 2004
Filed:
Apr 5, 2001
Appl. No.:
09/827052
Inventors:
Ronald John Krefta - Noblesville IN
James E. Walters - Carmel IN
Fani S. Gunawan - Westfield IN
Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
H02P 124
US Classification:
318727
Abstract:
Method and system for controlling a permanent magnet machine driven by an inverter is provided. The method allows for monitoring a signal indicative of a fault condition. The method further allows for generating during the fault condition a respective signal configured to maintain a field weakening current even though electrical power from an energy source is absent during said fault condition. The level of the maintained field-weakening current enables the machine to operate in a safe mode so that the inverter is protected from excess voltage.

System And Method For Clamp Current Regulation Of Induction Machines

View page
US Patent:
6850033, Feb 1, 2005
Filed:
Aug 26, 2003
Appl. No.:
10/649447
Inventors:
Gabriel Gallegos-Lopez - Alexandria IN, US
Fani S. Gunawan - Westfield IN, US
James E. Walters - Carmel IN, US
Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
H02P 528
US Classification:
318807, 318801, 318800
Abstract:
A device to regulate current produced by an induction machine responsive to a plurality of phase current signals. The motor produces torque for application on a shaft. A processing and drive circuit responsive to a direct current command signal and a quadrature current command signal produces phase current signals for input to the motor. A command circuit responsive to the phase current signals, an angular position of said shaft, and a voltage input command signal to produce a direct current error signal and a quadrature current error signal. A control circuit responsive to the direct and quadrature current error signals produces the direct voltage signal command and the quadrature signal command. The control circuit has a direct and quadrature proportional gain, integrator and clamp circuits. An algorithm produces limited or clamped voltage modulation index signals to obtain maximum efficiency and maximum torque per ampere in the speed range.

Method And Controller For Field Weakening Operation Of Ac Machines

US Patent:
6876169, Apr 5, 2005
Filed:
Jan 14, 2003
Appl. No.:
10/341997
Inventors:
Gabriel Gallegos-Lopez - Alexandria IN, US
James E. Walters - Carmel IN, US
Fani S. Gunawan - Westfield IN, US
Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
H02P007/36
US Classification:
318701, 318609, 318811, 318254, 3889281
Abstract:
Method for providing current regulation and a current controller () for an electric machine () are provided. The method includes receiving a state vector time signal () indicative of a time interval when a switching state vector is activated and comparing the received state vector time signal to a commanded state vector time signal (). The method further includes using the result of the comparison to regulate a direct axis current signal () input to an electric machine controller. The current controller () includes a state vector error comparator for comparing a received state vector time signal to a commanded state vector time signal and generating a state vector time error. This error is processed by a PI controller, coupled to the state vector error comparator, for providing a direct axis current signal output responsive to the state vector time error to an electric machine.

US Patent:
6407531, Jun 18, 2002
Filed:
Jan 9, 2001
Appl. No.:
09/757187
Inventors:
James E. Walters - Carmel IN
Fani S. Gunawan - Westfield IN
Yanhong Xue - Westfield IN
Assignee:
Delphi Technologies, Inc. - Troy MI
International Classification:
H02P 700
US Classification:
318805, 318807
Abstract:
System and method for controlling a synchronous machine are provided. The method allows for calculating a stator voltage index. The method further allows for relating the magnitude of the stator voltage index against a threshold voltage value. An offset signal is generated based on the results of the relating step. A respective state of operation of the machine is determined. The offset signal is processed based on the respective state of the machine.
