System and method for controlling torque ripples in synchronous machines

摘要

A system for controlling torque ripple in a permanent magnet synchronous machine (14) includes a power converter (18) configured to be coupled to the machine and configured to receive converter control signals and a system controller (20) coupled to the power converter. The system controller is configured to supply power and/or torque control signals to the power converter to regulate the fundamental power and/or torque produced by the machine. The system controller is further configured to supply harmonic control signals to the power converter to reduce acoustic noise and/or torque ripple generated by the machine.
