摘要: 在文献自适应辨识预报和控制-多层递阶途经中,我们提出了非线性系统动态线性化 的概念.这种动态线性化仅仅是形式上的,而不是真的线性化.但研究发现,在这种线性化过程 中,包含了一种新的系统辨识思想,那就是在线实时建模一实时反馈控制校正的思想.这种辨识 把建模与反馈控制结合成为一体,突破了参数自适应的框架.实现了控制系统的结构自适应性, 并且避免了建立数学模型这一繁锁的步骤.本文就是对这种系统建模与控制一体化的途径进行 介绍.Abstract: In the concept of dynamical linearization of non-linear system proposed by the author, the dynamical linearization is only formal, but not a real linearization. From the linearization procedure, a new approach of system identification that is on-line real time modeling and real time feedback control correction can be found. The modeling and real time feedback control are united in the identification approach, and the pattern of parameter adaption is broken up. The structure adaptation of control system is achieved, so the complex modeling steps are avoided. The objective of this paper is to introduce the approach of unity of modeling and control.
