LINKING MULTIPLE INDEPENDENT CONTROL SYSTEMS TO DISTRIBUTE REPONSE
First Claim
1. A method of controlling an attribute of a computing device, comprising:
- determining a current value of the attribute associated with at least a portion of the computing device;
determining a plurality of control effort values based on the current value of the attribute for each controller of a plurality of independent linked controllers;
selecting a maximal control effort of the plurality of control effort values; and
applying the maximal control effort to manipulate the attribute.

Abstract
A linked multiple independent control system can include two or more independent controllers configured to cooperatively control operating points of a system. In one particular embodiment, the linked multiple independent control system can control operating temperatures of a computing device. In one embodiment, the independent controllers can operate in parallel to develop control effort signals that are used by the computing device to affect operating parameters of one or more components included in the computing device. In another embodiment, independent controllers can have independent temperature thresholds that can affect control effort signals only from the related controller.

9. A method of controlling a temperature of a computing device, comprising:
-
determining a current operating temperature of at least a portion of the computing device; computing a first temperature management effort value when the operating temperature is greater than a first temperature threshold, wherein the first temperature management effort value is limited to a first value; computing a second temperature management effort value when the operating temperature is greater than a second temperature threshold, wherein the second temperature threshold is greater than the first temperature threshold and wherein the second temperature management effort value is limited to a second value; and
,selecting the maximal value of the first and the second temperature management effort values. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
