摘要: 本文基于煤气流量与检测点处炉温间的多变量动态系统模型的在线辨识,对具有跟踪调 节炉温作用的煤气流量设计了最小方差自校正控制器,随时确定相应的最佳煤气流量,实现了 炉温的最优控制.仿真研究表明,本文方法能够满足控制要求.Abstract: 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.
