反馈与智能控制系统的结构

Feedback and the Structure of Intelligent Control System

“反馈”是自动控制中一个非常重要的概念和方法.在经典控制理论和现代控制理论中,反馈被用来产生作为控制器输入的误差.在智能控制系统中,复杂的控制对象和任务使得控制是由多种控制方案实现的.而在什么系统状态下采用什么控制方案的“决策”则是根据系统的“状态反馈”做出的.智能控制系统的状态反馈是反馈的更“聪明”的实现形式,是智能控制系统的重要“智能”特征.提出了一个基于反馈的智能控制系统的结构,并结合一个应用实例给出进一步的说明.

Feedback is an important concept and method in automation. In classical control theory and modem control theory, feedback is used to produce errors which is the input of a controller. In intelligent control system, complex controlled system and task specifications make the automation to be achieved by several control strategies. The decision on using what control strategy under what system condition depends on the state feedback of the system. State feedback of intelligent control system is a more clever realizing form of feedback and it is also an important intelligent characteristic for intelligent control system. A structure of intelligent control system based on feedback is proposed. An application case is given to explain the structure.
