The norm - bounded parametric uncertainties entered into system matrices , input matrices and interconnections in all of the t - s fuzzy subsystems . dpdc controllers are designed for the uncertain interconnected fuzzy large - scale systems and lmi - based decentralized robust stabilizable conditions for uncertain interconnected fuzzy large - scale systems are developed 所考虑的参数不确定性以范数有界的形式出现在各个子模糊系统的系统矩阵、输入矩阵及输出矩阵中,本论文讨论了该类不确定性关联大系统dpdc控制器的设计问题。
Third , controlling chaos in the chaotic n - scroll chua ' s circuit is studied . the approach taken is to use feedback of a single state variable in a simple pd ( proportional and differential ) format . first , the unstable fixed points in the n - scroll chua ' s circuit are classified into two different types according to the characteristics of the eigenvalues of the linearized system matrix at the fixed points 第三,研究了多涡卷chua电路中不动点处jacobian矩阵特征根的性质,并据此将不动点分成两类,应用变量的比例微分反馈法分别对这两类不动点的可控性进行了研究,研究发现该法只能实现第一类不动点及其相应子空间的混沌控制,而不能完成第二类不动点的混沌控制,并给出了数值模拟结果,理论分析和数值模拟证实了该方法的有效性。
Another method that combines singh algorithm with differential algebra also can decouple nonlinear systems . the method can find the certain part of output be decouplled structure of original system by singh algorithm calculating essentiality of the decouplled system matrix . being an example , the paper deduce the process of ac servo motor controlled by the method 另一种方法是采用singh算法与微分代数理论相结合对非线性系统进行解耦设计,通过对采用singh算法后得到的解耦系统的矩阵,来计算其本性耦合关系,寻找出某个分划是原非线性系统的解耦结构,并以交流伺服电动机为例进行了分析。
Because the fem approach generates a highly sparse system matrix and the po and ptd technique could obtain analytic solutions of rcs for the electrically large bodies , it is shown that the hybrid technique has some advantages over other methods in regard to saving computer memory units and cpu time 同时,应用po - ptd方法计算电大尺寸规则目标的散射场能得到散射场的解析表达式,所需计算机内存和计算电磁散射与辐射问题中基于矢量有限元的混合方法研究时间与目标电尺寸无关。
An explicit expression to compute h norm and obtain h controller , which are recently obtained for continuous - time state - space symmetric systems , are extended to more general case of continuous - time symmetric systems . the computations of h norm only need to compute the maximum eigenvalue of a symmetric matrix , which only contains the system matrices 把一最近文献得到的有关连续时间状态对称系统h ~范数和h ~控制器的明显解结果推广到更广泛连续时间对称系统,所得到h ~范数计算仅包括系统矩阵。
