1. A method comprising:

  • receiving, by an adaptive controller, performance measurement for a computing system;

    estimating, based at least in part on said received performance measurement, a plurality of different performance models;

    identifying at least one of said estimated performance models having a correct sign for approaching performance desired for said computing system;

    using one of said at least one identified performance models for determining a responsive action for said adaptive controller to take in response to said received performance measurement; and

    maintaining, by said adaptive controller, a correct sign for an estimated performance model that is used for determining said responsive action, even when an external event that is not accounted for in the estimated performance model impacts said performance measurement received for said computing system.
