Design and implementation of a microwave heating system based on dual-closed loop control strategy

Microwave energy has been widely applied to vast industrial applications as a novel, clean and efficient energy source. This paper illustrates the design and implementation of a microwave heating system, and a dual-closed loop control strategy is presented to regulate the microwave power. Further, several experimentations were carried out, experiment results show that the output microwave power is reasonable accurate to the expectation, and the sample temperature is controlled effectively.
