The Realization of Self-Tuning Temparature control for Reheating Furnace
连续加热炉炉温自校正控制的实现

Based on the on-line identification of the multivariable dynamic system between gas flow and furnace temperature at measuring points, we design a minimum variance self-tuning controller for gas flow which traces and regulates furnace temperature, so as to determine the corresponding optimal gas flow at all times, thus realizing the optimal control of furnace temperature. The simulation results completely satisfy the control requirements.
