Synchronization module for motor speed control

摘要

A system includes a first control system configured to operate at a first clock speed, a second control system configured to provide an output to the first control system and configured to operate at a second clock speed different from the first clock speed, and a synchronization module operatively connecting the first control module to the second control module and configured to synchronize the first control system and the second control system such that the output of the second control system is timed to synchronize with the first clock speed.

1. A system, comprising:
a first control system configured to operate at a first clock speed; a second control system configured to provide an output to the first control system and configured to operate at a second clock speed different from the first clock speed; a synchronization module operatively connecting the first control module to the second control module and configured to synchronize the first control system and the second control system such that the output of the second control system is timed to synchronize with the first clock speed; and an electric motor operatively connected to the second control system; wherein the system is configured to:
start a loop sample timer to sample the clock speed of the first control system or to track the clock speed of the first control system;receive speed data regarding the speed of the electric motor;calculate error of the speed of the electric motor as compared to a speed command;generate a new duty cycle command for input into the first control system; andinput the new duty cycle command into the first control system upon completion of the loop sample timer.
