A NEW METHOD FOR DESIGNING CHARACTERISTIC MODELS OF INTELLIGENT CONTROLLERS

特征模型的设计是仿人智能控制理论中十分重要的组成部分之一 .文中从某些时域性能指标出发 ,提出了一种设计 (e- t)信息空间特征模型的新方法 .通过引入特征点、特征直线等概念 ,直接建立了仿人智能控制的特征模型与系统的上升时间 tr、超调量 δp 和峰值时间 tp 等性能指标的定量关系 ,并用于实时调整特征状态的切换阈值 ,实现了对特征模型的动态设计 .

Designing of characteristic models is a very important part of human simulating intelligent control (HSIC) theory. The paper presents a new method based on some time domain performances for designing characteristic models in ( e-t ) information space by means of characteristic lines and characteristic points which are introduced concepts. The quantitative relation between characteristic models of HSIC and some time domain performances (e.g., rising time t r, overshoot δ p, peak time t p ) is set up directly and is used for adjusting the threshold of switching among the characteristic states. The dynamic designing of characteristic models is thus implemented, and the results of simulations show the suitability and effectiveness of the method.
