利用铁粉铝粉间的放热化学反应合成了Fe3Al合金,分析比较了热爆、热爆加压和自蔓延三种工艺条件下产物形成过程及组织结构特点,研究表明:合成开始时首先分别在粗大铁粉和细小铁粉处形成含铝富铁。相和n(Fe3Al5)型化合物两种过渡相,热爆合成温度较高,两种过渡相间可充分反应生成成份均匀的a相,并经较快冷却后亚稳定存在于室温;热爆加压合成时,加压系统的吸热不仅使合成反应移到温度较低的B2相区中进行,而且冷却加快使反应后的扩散过程无法充分进行,产物由成份不均匀的B2相和反应后残留的a相组成。

This paper proposes a new type of generalized predictive controller. Because there is a dynamic tuning to the prediction error in the controller design, and the proportional integration type cost function is used, so the controller has strong robustness to unmodelled dynamic. The effectiveness of the method is verified by the simulation research on a strong heat-releasing chemical reactor during which a lower order model is configurated.

提出了一种新型的广义预测控制器。由于在控制器的设计中,进行了预测误差的动态校正,并且控制器采用了比例积分型(PI)目标函数,因此该控制器对未建模动态具有很强的鲁棒性。应用低阶的模型对一个强放热的化学反应釜模型进行的仿真研究检验了该方法的有效性。
