本文以置式退火炉为对象,根据其退火过程的输入输出数据,用系统辨识的方法,建立了线性动态模型。在此基础上,根据最佳控制理论,导出了节能控制规律——开关控制。结合对象的传热特点,用峰值预极的方法解决了开关状态的选择问题。计算机仿真结果表明,采用上述方法控制,节能效果在5％以上。 In this paper, the home annealing furnace as the object, according to the input and output data of its annealing process, using the method of system identification, established a linear dynamic model. On this basis, according to the best control theory, the energy-saving control law is derived - switch control. Combined with the heat transfer characteristics of the object, the problem of selection of the switch state is solved by the method of peak prepolarization. Computer simulation results show that using the above method of control, energy-saving effect of more than 5%.
