【中文文摘】 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δ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阂值.实现了对待征模型的动态设计.仿真实验结果表明了该方法的适用性和有效性.
【英文文摘】 Designing of characteristic models is a very important part of human-simulating-intelligent contro1(HSIC)theory. The paper presenst 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.,risingtime tr,oversh- ootδ,peak time tp)is set uP directly and is used for adjusting the thresho1d of switching among the characteristic states. The dynamic designing of characteristic models is thus impl- emented,And the results of simulations show the suitability and effectiveness of the method.
