Study on Dynamic Calibration and Dynamic Compensation Technique of the Thermocouple based on quantum-behaved particle swarm algorithm

In order to improve the dynamic characteristics of the thermocouple sensor effectively by the dynamic cal?ibration and dynamic compensation technique,the temperature sensor’s traceable dynamic calibration system was constructed by taking advantage of the characteristics of high and quick heating of the semiconductor laser,which made the traceable dynamic calibration of the thermocouple to come true. Then,the time constant of the C-type ther?mocouple was measured by this system. At the same time,a model of the dynamic compensation filter was designed for the thermocouple sensor based on the quantum particle swarm optimization(QPSO)algorithm,which was terri?fied its great efficiency in reduction of the dynamic errors and could be used to improve the dynamic characteristics of the thermocouple.
