近几十年来,现代控制理论日趋成熟,要将这些理论成果应用于过程控制,就必须借助于电子计算机,完成在线的复杂运算。最近,我们在DJS—131机上对原有BASIC解释系统软件进行了改造和扩充,使之适用于实时过程控制。本文着重介绍一个用过程BASIC编制的递推辨识和信号发生程序,监应用于具体压力—液位对象的实时辨识。 In recent decades, modern control theory matures. To apply these theoretical results to process control, it is necessary to use electronic computers to complete online complex operations. Recently, we modified and expanded the original BASIC interpretation system software on the DJS-131 to make it suitable for real-time process control. This article focuses on a recursive identification and signal generation program written in the BASIC process that monitors the real-time identification of a specific pressure-level object.
