Abstract
A fuzzy logic-based system and method for controlling the drying of material by a microwave applicator. The system includes power output controller that controls applicator output power; material sensor that detects amount of material in the applicator; and fuzzy logic controller that receives a signal from the material sensor indicating the current amount of material in the applicator and adjusts the microwave output power based on the current amount of material in accordance with fuzzy logic rules by sending a control signal to the power output controller. A membership function divides the expected range for the amount of material into multiple regions, each region having precomputed regional output settings. The regional output settings of the regions that include the current amount of material are used to compute the control signal.
