真空钎焊炉系统辨识及应用

System Identification and Application of the Vacuum Soldering Furnace

利用逆M伪随机序列信号,选用最小二乘算法、辅助变量算法及模型参考自适应算法、离线辨识,建立大型真空钎焊炉数学模型的过程。给出了最终确立的线性数学模型。根据这一模型设计的温控系统数字调节器在实际应用中达到了十分满意的效果。

Using the inverse M pseudo-random series signal, the least-square method, the auxiliary variable algorithm, the model reference self-adjustment algorithm and the off-line i-dentification, the linear mathematical model for a large-scale vacuum soldering furnace has been established. The designed digital adzustor for temperature control system, according to this model, has also been applied satisfatorily.
