前言在前面两讲中,我们讨论了自校正方法在过程控制中的应用。自校正方法是一种比较实用的适应控制方法。由于它具有方法简单便于执行的优点,近年来在过程控制中得到了广泛地应用。无疑推广这一类系统,对进行过程控制的计算机系统的研制是会有好处的。但是,任何一种控制方法都有其一定的适用范围,自校正控制也是如此。它主要是解决慢时变线性系统的调节问题。而在过程控制中所遇到的被控过程和控制目标却是多种多样的。因此,为了解决好过程控制中的各种难题,也就需要有多种方法。
Preface In the previous two lectures, we discussed the application of self-tuning methods in process control. Self-calibration method is a more practical method of adaptive control. Because of its simplicity and ease of implementation, it has gained widespread use in process control in recent years. There is no doubt that the promotion of this type of system will be of benefit to the development of computer systems for process control. However, any one of the control methods has its own scope of application, self-tuning control as well. It is mainly to solve the slow time-varying linear system regulation problem. In the process of control encountered in the controlled process and control objectives are varied. Therefore, in order to solve the various problems in process control, it also needs a variety of methods.
