本文描述了一种称为“监控器”的简单“高级”控制器，它能够通过 SISO 过程、一系列候选控制器中的线性定位或设定点控制器切换到反馈，从而使过程的输出接近并跟踪恒定的参考输入。假设该过程由 SISO 线性系统建模，其传递函数是多个子类的并集，每个子类足够小，以便如果过程的传递函数是子类的成员之一，则候选控制器之一将解决定位问题。每个子类都包含一个“标称过程模型传递函数”，该子类以该函数为中心。结果表明，在没有未建模的过程动态的情况下，即使存在过程扰动，所提出的监控器也可以成功地执行其功能，只要它们是有界的且恒定的。
This paper describes a simple "high-level" controller called a "supervisor" which is capable of switching into feedback with a SISO process, a sequence of linear positioning or set-point controllers from a family of candidate controllers so as to cause the output of the process to approach and track a constant reference input. The process is assumed to be modeled by a SISO linear system whose transfer function is in the union of a number of subclasses, each subclass being small enough so that one of the candidate controllers would solve the positioning problem if the transfer function of the process were to be one of the subclasses' members. Each subclass contains a "nominal process model transfer function" about which the subclass is centred. It is shown that in the absence of unmodeled process dynamics, the proposed supervisor can successfully perform its function even if process disturbances are present, provided they are bounded and constant.
