自从模糊逻辑引入到过程控制后,模糊控制器的设计一般延用Zadeh的综合规则推理。在多输入多输出的多变量系统中,这种方法暴露出了它的弱点。本文提出了另一种模糊控制器的设计方法——分类建立过程的控制模型,并着重讨论了如何建立控制模型。后面的例子说明了在某一类系统的控制器设计中采用这种方法是比较有效的。 Since the introduction of fuzzy logic into the process control, the design of fuzzy controller is generally extended with Zadeh’s comprehensive rule reasoning. In multivariate systems with multiple inputs and multiple outputs, this approach reveals its weaknesses. In this paper, we propose another design method of fuzzy controller - the control model of classification establishment process, and emphatically discuss how to set up the control model. The latter example shows that it is more efficient to adopt this method in the controller design of a certain type of system.
