Study of Fuzzy-PID control and Simulation of Electrical Heating in Calibration Device for Heatmeters

摘要

The temperature control method of electrical heating is utilized,which adopts Fuzzy-PID control arithmetiC and realizes steady temperature control by controlling the heating power. The Fuzzy-PID control of electrical heating in the calibration system for large diameter heatmeters is simulated in this paper. Its results indicate that the control method,whose control precision is between ±0.1 'C,can improve the temperature stability,reduce the energy consume,and good robustness.
