1. A method of controlling cooling of an electronic system, the method comprising:

  • automatically determining control settings for multiple adjustable cooling components of a cooling system cooling the electronic system, the automatically determining control settings being based, at least in part, on weighted cooling effectiveness of the multiple adjustable cooling components of the cooling system, the automatically determining control settings providing determined control settings;

    wherein the automatically determining control settings operates to limit power consumption of at least the cooling system, while ensuring that a target temperature associated with at least one of the cooling system or the electronic system is within a desired range by provisioning, based at least in part, on the weighted cooling effectiveness, a desired target temperature change among the multiple adjustable cooling components, the provisioning including provisioning applied power to the multiple adjustable cooling components via, at least in part, the determined control settings;

    wherein the automatically determining control settings comprises automatically determining speed control settings for the multiple adjustable cooling components of the cooling system to provide determined speed settings, each adjustable cooling component n of the multiple adjustable cooling components comprising an adjustable speed control, and wherein the provisioning includes provisioning the applied power to the multiple different cooling components via, at least in part, the determined speed settings;

    wherein the automatically determining control settings further comprises ascertaining the desired target temperature change for a particular time to facilitate maintaining the target temperature within the desired range, and obtaining a weighting ratio of cooling effectiveness of adjustable cooling component n to a total cooling effectiveness of the multiple adjustable cooling components, and a proportional gain for adjustable cooling component n of the multiple adjustable cooling components and, based at least in part thereon, determining the speed control settings for the multiple adjustable cooling components of the cooling system to achieve the desired target temperature change; and

    wherein determining the speed control setting for adjustable cooling component n of the multiple. adjustable cooling components comprises determining a change in speed control setting for adjustable cooling component n, the change in speed control setting for adjustable cooling component being determined as;
