Abstract
A method of controlling a compressor includes measuring a pressure of fluid entering the compressor, measuring a pressure of fluid exiting the compressor, and measuring a rotational speed of the compressor. Signals indicative of the measured pressure of fluid entering the compressor, measured pressure of fluid exiting the compressor, and measured rotational speed of the compressor are sent to an electronic control unit. The operation of the compressor is controlled in response to at least the signal indicative of the measured rotational speed of the compressor received by the electronic control unit.

A method of controlling a compressor, comprising:
- measuring a pressure of fluid entering the compressor;
- measuring a pressure of fluid exiting the compressor;
- measuring rotational speed of the compressor;
- sending signals indicative of the measured pressure of fluid entering the compressor, measured pressure of fluid exiting the compressor, and measured rotational speed of the compressor to an electronic control unit;
- and
- controlling the operation of the compressor in response to at least the signal indicative of the measured rotational speed of the compressor received by the electronic control unit, wherein the controlling of the operation of the compressor includes bypassing fluid exiting the compressor to an inlet line of the compressor.
