Abstract
A method for controlling a linear compressor of an appliance includes receiving, via a controller of the linear compressor, a d-axis current error signal, a q-axis current error signal, and a DC current error signal. The method also includes determining, via the controller, a DC voltage component signal based on the DC current error signal. The DC voltage component signal is limited by a first voltage threshold. Further, the method includes then determining, via the controller, a d-axis voltage component signal based, at least in part, on the q-axis current error signal. The d-axis voltage component signal is limited by a second voltage threshold. Furthermore, the method includes then determining, via the controller, a q-axis voltage component signal based, at least in part, on the d-axis current error signal. The q-axis voltage component signal is limited by a third voltage threshold that is less than the second voltage threshold. In addition, the method includes controlling, via the controller, a motor of the linear compressor using a single-phase vector-like control scheme based, at least in part, on the DC voltage component signal, the d-axis voltage component signal and the q-axis voltage component signal.
