Abstract

A new philosophy of identification for use in control design is proposed. The current philosophy consists of attempts to find the single best plant model at each time. An example demonstrates the serious problems that may result from using a single model in a control law during the transient phase of identification when this model is not likely to be correct. The new philosophy proposes maintaining a set of possible plant models and eliminating models which are inconsistent with incoming data. The model set should then shrink so that control laws which provide improved performance for the entire model set become possible.<>

反思20世纪90年代的自适应控制
提出了一种用于控制设计的新的识别理念。目前的理念是每次都试图找到一个最好的植物模型。一个例子表明,在辨识的瞬态阶段,当模型不太可能正确时,在控制律中使用单个模型可能会导致严重的问题。新的理念建议保留一组可能的植物模型,并消除与输入数据不一致的模型。然后,模型集应该缩小,以便为整个模型集提供改进性能的控制律成为可能
