摘要： Methods and apparatus for drying ceramic green bodies include providing one or more ceramic green bodies in a microwave heating chamber operatively connected to a microwave source and a PLC. The total mass of the ceramic green bodies present in the microwave heating chamber is determined. Microwave energy is generated with the microwave source and transmitted from the microwave source to the microwave heating chamber. A transmitted power of the microwave energy transmitted from the microwave source to the microwave heating chamber is measured with power sensors. The reflected power of reflected microwave energy reflected back from the microwave heating chamber is also measured. The power of the microwave energy transmitted from the microwave source to the microwave heating chamber is adjusted based on the total mass of ceramic green bodies present in the microwave heating chamber, the measured transmitted power and the measured reflected power.

摘要： Methods and apparatus for microwave drying of green cellular ceramic bodies (logs) using feedback and feed forward control are disclosed. The methods include measuring an amount of dissipated microwave power and measuring temperatures of the logs and inputting this information into a drying model. The drying model accounts for at least a heat capacitance, a water content and a mass of the logs, and relates changes in the dissipated microwave power to changes in the log temperature. The changes in microwave power generated by the adjustable microwave source are thus based on the calculated dissipated power changes.

摘要： 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.
