For a large scale of linear time - invariant systems , linear time - varying systems and nonlinear systems , many scholars proposed a series of new schemes 针对一大类线性时不变系统,线性时变系统及非线性系统,许多学者利用backstpping方法提出了一系列新的非线性控制器设计方案
Abstract : the paper shows the relative deformation function of the cam mechanism with a roller follower as a linear time - invariant system , and gives the detail about the response limitation for the dynamic design and modification of cam mechanisms . an example demonstrates this approach can improve the flexible cam mechanisms 文摘:以滚子从动件平面凸轮机构为分析对象,提出了相对变形函数这一新概念,并从理论上对其进行了研究,最后借助于一凸轮机构在不同参数下其摆臂最大相对变形量的数值计算过程与结果,阐述了基于该理论的凸轮机构动态设计与修改的具体实现步骤与方法。
Based on the lyapunov approach , my main results are obtained as follows : 1 . the decoupling of the linear time - invariant system and linear time - delay system are discussed . for linear systems with norm - bounded uncertainties , conditions for energy decoupling with input transformation or both state feedback and input transformation are given in terms of linear matrix inequalities 讨论了线性定常系统和时滞系统的能量解耦,研究了具有范数有界不确定参数的线性不确定系统,给出了不确定线性系统仅具有输入变换、同时具有状态反馈和输入变换情况下的能量解耦方法,结果以线性矩阵不等式的形式给出。
