Patent number: 11926221Abstract: A method for controlling transient operation of a variable flux machine (VFM) includes, during a shunt angle transition, receiving a commanded and measured shunt angle when operating in a predetermined operating region, e.g., maximum torque per ampere or field weakening. The method includes calculating d-axis and q-axis delta current terms (?Id and ?Iq) required to maintain an output torque level of the VFM through a duration of the shunt angle transition, then applying the required ?Id and ?Id terms as feed-forward terms to adjust a d-axis current (Id) term and a q-axis current (Iq) term from a respective lookup table. In this manner the controller maintains the output torque level of the VFM during the shunt angle transition. An electric powertrain includes the VFM, a TPIM, and the controller. A PM machine may be controlled by substituting temperature for shunt angle.Type: GrantFiled: September 24, 2020Date of Patent: March 12, 2024Assignee: GM Global Technology Operations LLCInventors: Xin Jing, Bojian Cao, Brent S.

Patent number: 11316391Abstract: 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.Type: GrantFiled: March 2, 2020Date of Patent: April 26, 2022Assignee: GM Global Technology Operations LLCInventors: Xin Jing, Bojian Cao, Brent S.

Patent number: 10164563Abstract: An electric power system for supplying power to a permanent magnet electric machine includes a high-voltage DC power source that is disposed to supply electric power to a front-end converter connected via a high-voltage DC bus to an electric inverter that is connected to the electric machine. A method for operating a control system includes monitoring the electric machine. Upon detecting a fault associated with the electric machine, a controller commands operation of the front-end converter to generate a voltage level on the high-voltage DC bus that is a maximum setpoint voltage level and monitors back-emf voltage level from the electric machine. The inverter is controlled to a three-phase open state when the back-emf voltage level is less than the maximum setpoint voltage level. The inverter is controlled to a three-phase short state when the back-emf voltage level is greater than the maximum setpoint voltage level.Type: GrantFiled: April 15, 2016Date of Patent: December 25, 2018Assignee: GM Global Technology Operations LLCInventors: Xin Jing, Brian A.

Patent number: 9774288Abstract: An electric machine assembly includes an electric machine, an inverter configured to provide pulse-width modulation characterized by a switching frequency and a controller. The controller has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method of controlling the switching frequency to minimize a beat frequency phenomenon. Execution of the instructions by the processor causes the controller to obtain a first function (G1) and a second function (G2) based at least partially on the original pulse ratio (PR0). The original pulse ratio (PR0) is a ratio of the switching frequency and a predefined fundamental frequency. If each of a plurality of conditions are met, a new pulse ratio (PRN) is determined based at least partially on the original pulse ratio (PR0), the first function (G1) and the second function (G2).Type: GrantFiled: August 2, 2016Date of Patent: September 26, 2017Assignee: GM Global Technology Operations LLCInventors: Xin Jing, Brian A.
