1. An on-board inert gas generation system comprising:

  • an air separation module configured to produce nitrogen enriched air from non-enriched air, the air separation module having a desired operating temperature range;

    a compressor system in fluid communication with the air separation module, the compressor system configured to rotate at a speed and provide the non-enriched air to the air separation module; and

    a controller in communication with the compressor system, the controller configured to reduce the speed in response to a parameter reaching an undesired value that would produce a non-enriched air temperature that would exceed the desired operating temperature range, the reduced speed selected to maintain the non-enriched air temperature within the desired operating temperature.
