众所周知,具有纯滞后动态特性的对象或过程是常规调节规律难以控制的。为了解决这类对象的控制问题,长期以来人们一直致力于这方面的研究工作,并不断提出新的方案与方法。比如,1957年,Smith 提出了连续控制系统的预报补偿控制方案;1969年,Moore 针对数字计算机采样控制系统的特点,利用电子计算机快速计算的能力,提出了解析预报控制方案。在他们工作的基础上,笔者前两年曾提出一种响应系数预报控制方法。最近一段时间,我们又对纯滞后对象的 DMC(Dynamic Matrix Con-tiol)预报控制作了一些研究,取得了令人满意的结果。
It is well known that objects or processes with purely delayed dynamics are uncontrollable by conventional regulation. In order to solve the control problem of such objects, people have been devoting themselves to research work in this field for a long time and have continuously come up with new solutions and methods. For example, in 1957, Smith proposed a predictive compensation control scheme for a continuous control system. In 1969, Moore proposed a predictive control scheme based on the characteristics of a digital computer sampling control system and the ability to quickly calculate it using electronic computers. On the basis of their work, the author proposed a control method of response coefficient forecast two years ago. In the recent period, we made some researches on DMC (Dynamic Matrix Con-tiol) forecast control of purely lagged objects and achieved satisfactory results.
