Cooking appliance and method for closed-loop cooking operation

A controller for a cooking appliance, the controller configured to control a heating operation of the cooking appliance, the heating operation comprising:

• acquiring a first command signal corresponding to initiating a closed-loop cooking operation;
• acquiring, during the closed-loop cooking operation, a feedback parameter for controlling the heating operation;
• acquiring a second command signal corresponding to terminating the closed-loop cooking operation;
• acquiring, during a buffer period initiated from acquiring the second command signal, the feedback parameter for controlling heating operation;
• determining, after acquiring a third command signal during the buffer period, a control output for controlling the heating operation based on the feedback parameter acquired during the buffer period;
• and
• clearing memory associated with the feedback parameter acquired during the buffer period if the third command signal is not acquired during the buffer period.

A method for controlling heating operation for a cooking appliance, the method comprising:

• acquiring a first command signal corresponding to initiating a closed-loop cooking operation;
• acquiring a feedback parameter for controlling the heating operation of the heating element;
• acquiring a second command signal corresponding to terminating the closed-loop cooking operation;
• acquiring, during a buffer period initiated from acquiring the second command signal, the feedback parameter for controlling the heating operation of the heating element;
• acquiring, during the buffer period, a third command signal corresponding to initiating the closed-loop cooking operation;
• restoring, after acquiring the third command signal, the closed-loop cooking operation based on the feedback parameter acquired during the buffer period;
• and
• terminating acquisition of the feedback parameter after the buffer period elapses if the third command signal is not acquired during the buffer period.
