Reduced Control Cycle Current Regulator For Vehicle Electric Traction Motor

View page
US Patent:
20230022957, Jan 26, 2023
Filed:
Jul 21, 2021
Appl. No.:
17/381906
Inventors:
- Detroit MI, US
Lei Hao - Troy MI, US
Suresh Gopalakrishnan - Troy MI, US
Bojian Cao - Troy MI, US
Vinod Chowdary Peddi - Shelby Township MI, US
International Classification:
H02P 27/08
B60L 50/60
B60K 6/22
Abstract:
A system in a vehicle includes a current regulator to obtain current commands from a controller based on a torque input and provide voltage commands and an inverter to use the voltage commands from the current regulator and direct current (DC) supplied by a battery to provide alternating current (AC). The system also includes an electric traction motor to provide drive power to a transmission of the vehicle based on injection of the AC from the inverter. The current regulator adjusts parameters of a transfer function implemented by the current regulator, based on feedback of an input to and an output from the electric traction motor to achieve the AC corresponding with the torque input in no more than two control cycles.

Closed-Loop Control For Transient Operation Of Variable Flux And Permanent Magnet Electric Machines

US Patent:
20210273505, Sep 2, 2021
Filed:
Mar 2, 2020
Appl. No.:
16/806354
Inventors:
- Detroit MI, US
Bojian Cao - Troy MI, US
Brent S. Gagas - Ferndale MI, US
Assignee:
GM GLOBAL TECHNOLOGY OPERATIONS LLC - Detroit MI
International Classification:
H02K 1/27
H02K 1/24
H02M 7/48
Abstract:
A method for controlling transient operation of a rotary electric machine in an electric powertrain or other electrical system includes, during a shunt angle transition occurring during a maximum torque per ampere (MTPA) control region, determining an estimated output torque of the electric machine via a torque estimation block using d-axis and q-axis current commands and an additional value, i.e., an actual shunt angle or a machine temperature. The method includes subtracting the estimated output torque from a commanded output torque to derive an adjusted commanded torque value or torque error, and calculating, from the torque error, a delta d-axis current command and a delta q-axis current command. The method includes adjusting d-axis and q-axis current commands using the delta commands to produce adjusted d-axis and q-axis current commands, which are then used as closed-loop feedback control terms by the torque estimation block.
