A system and method for active disturbance rejection based thermal control is configured to receive, at a first active disturbance rejection thermal control (ADRC) controller, a first temperature measurement from a first thermal zone. The ADRC controller generates a first output control signal for controlling a first cooling element, wherein the first output control signal is generated according a first estimated temperature and a first estimated disturbance calculated by a first extended state observer (ESO) of the first ADRC controller.

Custom cooling strategies may be implemented for different regions in computers, servers, and other information handling systems. Chassis architecture may have multiple cooling fans, with each fan cooling a different region via dedicated duct work. A user or administrator may thus implement different cooling strategies for internal components, based on different thermal curves defined for each different region.

A cooking appliance includes a housing that defines a cooking cavity. A first temperature sensor is coupled to the housing and is configured to detect an air temperature of the cooking cavity. A rack is disposed within the cooking cavity and includes a second temperature sensor that is coupled to a frame of the rack.

When heating is being performed, and a temperature detected by a temperature sensor is lower than a first determination value, a controller opens the flow rate control valve corresponding to a heat exchanger, of the third heat exchangers, to which a request for air conditioning has not been made, and closes the flow rate control valve corresponding to a heat exchanger, of the third heat exchangers, to which the request for air conditioning has been made. When heating is being performed, and the temperature detected by the temperature sensor is higher than a second determination value, the controller opens the flow rate control valve corresponding to the heat exchanger to which the request for air conditioning has been made, and closes the flow rate control valve corresponding to the heat exchanger to which the request for air conditioning has not been made.
