Energy usage controller for an appliance

摘要

A controller controls the energy of an appliance during a current selected cycle in order to ensure that the energy usage is maintained below a predetermined average limit. The controller maintains the appliance's energy usage below the predetermined average limit by responding to an estimate of an expected average use. The expected average energy use is based on energy expected to be used by the appliance during the current selected cycle and stored energy use of the appliance during past selected cycles.
