基于预估比较原理的动态自寻最优控制系统

Review of Self-optimizing Control System Based on Pre-estimating Comparative Theory

介绍了自寻最优控制系统的基本概念、自寻最优控制的一些典型工业实例、自寻最优控制与反馈控制的不同之处,同时概述了自寻最优控制早期的各种静态寻优方法以及在实际工业生产控制过程中所遇到的障碍,并简要介绍了国内外在动态寻优方法方面的发展与创新,着重介绍了我国学者所提出的以预估比较原理为基础的动态寻优方法,以及在此基础上所提出的以保证控制系统运行的连续性与稳定性的自适应动态寻优方法.同时也简要介绍了在控制对象模型简化基础上所提出的一种简捷、高效、实用的自适应动态寻优方法.

The basic concept of self-optimizing,the typical industrial examples and the difference between the self-optimizing and feed control system are introduced,and every static optimizing in the early research and obstacles in the real industrial process control are also introduced. The new development of dynamic self-optimizing method at home and abroad is reviewed,the dynamic self-optimizing method based on pre-estimating comparative theory proposed by Chinese scholar is highlighted,and the self-adaptive dynamical optimizing method based on it is also introduced,which could keep a continuous and stable operation of the system by u- sing the method. It is also expected that this method will play an important role in the desirable industrial process control. It also provides an overview of a simple,efficient,and practical adaptive dynamic optimizing method based on simplified model of the con- trol plant.
