The design of output feedback H(subscript ∞) controllers is discussed for nonlinear discrete singular systems. First of all, by means of generalized Lyapunov function and linear matrix inequalities, zero solution E-asymptotically stable is studied for the system, a sufficient condition is given such that the system is zero solution E-asymptotically stable and a H(subscript ∞) norm constraint. And the output feedback H(subscript ∞) controller is designed to guarantee the performance of the resulting closed-loop system.

主要对非线性离散广义系统的输出反馈H控制器的设计问题进行讨论，首先利用广义Lyapunov函数和线性矩阵不等式，对系统的零解E-渐近稳定性问题进行分析，在此条件基础上给出系统零解E-渐近稳定且具有H范数约束的充分条件，然后设计系统的输出反馈H控制器，使得闭环系统具有同样的性能。

However, the area is less studied than other areas of endophyteresearch world wide. Therefore, a series of experiments were carried out in laboratory,glasshouse and field to compare the responses of endophyte infected plants andendophyte free plants of perennial ryegrass varieties to 10 fungal pathogensisolated from turf type ryegrass in Lanzhou. The pathogens used in the experimentswere Alternaria alternata、Bipolaris sorokiniana、Fusarium avenaceum、Curvularialunata、Ascochyta leptospora、Fusarium acuminatum、Fusarium chlamydosporum、Fusarium oxysporum、Fusarium solani and Gliocladium roseum. In addition, someprotective enzymes activity and alkaloids contents of E+ and E- plants were measuredand LpsA gene of the common strain - Lp19 and mutant strain -AR1 of Neotyphodiumlolii were sequenced to identify their ...
