  • Patent number: 11305810
    Abstract: Technical solutions for controlling operation of an electric machine by a control system are provided. The control system comprises an inverter and a controller performing a first operation to produce a first output data representing a motor control current command in a first time period beginning at one of a plurality of initial times occurring at a first periodic timing interval. The controller also performs a second operation upon the first output data to produce a second output data in a second time period. The controller also performs a third operation at a periodic command time to produce a motor control voltage command using the second output data in response to satisfaction of a timing criterion. The timing criterion is based upon comparing the command time and occurrence of a posting time after the initial time. A method of enforcing timing restriction to synchronize non-deterministic motor control events is also provided.
