Abstract
Controlling an activation status of a proportional-integral-derivative (PID) controller for an information handling system cooling system, such as the on/off status of the PID controller, can reduce power consumption and processing and memory requirements for such a system. A decrease in resource consumption can be realized by deactivating the PID controller during certain periods and activating the PID controller during others. For example, the PID controller can be deactivated when a temperature of a system component falls below a threshold temperature and activated when the temperature of the system component rises above the threshold temperature.
Claims20
A method for controlling a component cooling system of an information handling system, comprising:
- receiving a process value of a system component;
- comparing the process value of the system component to a set process value;
- activating a proportional-integral-derivative (PID) controller configured to generate a control signal for a cooling fan when the comparison indicates that a temperature of the system component is greater than or equal to a threshold temperature;
- and
- deactivating the PID controller when the comparison indicates that the temperature of the system component is less than the threshold temperature.
An apparatus, comprising:
- a controller configured to perform steps comprising:
- receiving a process value of a system component;
- comparing the process value of the system component to a set process value;
- activating a proportional-integral-derivative (PID) controller configured to generate a control signal for a cooling fan when the comparison indicates that a temperature of the system component is greater than or equal to a threshold temperature;
- and
- deactivating the PID controller when the comparison indicates that the temperature of the system component is less than the threshold temperature.
An apparatus for controlling a component cooling system of an information handling system, comprising:
- a cooling fan;
- and
- a controller coupled to the cooling fan to control the cooling fan;
- wherein, the controller is configured to perform steps comprising:
- receiving a process value of the system component;
- comparing the process value of the system component to a set process value;
- and
- activating a proportional-integral-derivative (PID) controller configured to generate a control signal for a cooling fan when the comparison indicates that a temperature of the system component is greater than or equal to a threshold temperature;
- and
- deactivating the PID controller when the comparison indicates that the temperature of the system component is less than the threshold temperature.
