摘要：The landing task of an aircraft under low aerodynamic pressure on carrier requires precise airplane control,A flight/thrust integrated control system(FTICS)with constant ad,actual angle of attack,is developed using LMI-based H∞*** typical single input/outputspecifications are translated into the weighting functions of an H∞output-feedback synthesis *** motiva-tion of the work is to improve the key performance of dy-namic tracking and air disturbance *** FTICS can keep the attitude andgle and the path angle un-changeable as the airplane is passing through the ramp at which the tracking radar doesnot work and the guidance signal is *** engineering application,an or-der-reduction method of the H∞controller is also pro-posed,Simulational results indicate that the system satis-fies the design requirements quite well.

摘要：In this paper, we examine the problem of designing power system stabilizer (PSS). A new technique is developed using particle swarm optimization (PSO) combined with linear matrix inequality (LMI). The main feature of PSO, not sticking into a local minimum, is used to eliminate the conservativeness of designing a static output feedback (SOF) stabilizer within an iterative solution of LMIs. The technique is further extended to guarantee robustness against uncertainties wherein power systems operation is changing continuously due to load changes. Numerical simulation ahs illustrated the utility of the developed technique.

摘要：This paper is concerned with the design problem of non-fragile controller for a class of two-dimensional (2-D) discrete uncertain systems described by the Roesser model. The parametric uncertainties are assumed to be norm-bounded. The aim of this paper is to design a memoryless non-fragile state feedback control law such that the closed-loop system is asymptotically stable for all admissible parameter uncertainties and controller gain variations. A new linear matrix inequality (LMI) based sufficient condition for the existence of such controllers is established. Finally, a numerical example is provided to illustrate the applicability of the proposed method.

摘要：针对线性奇异时滞系统的时滞相关稳定性问题,提出了一种新的方法来讨论,与之前的方法相比较,这种方法研究出的结果具有较小的保守性。首先将奇异系统转化为带有线性约束的中立系统;其次应用Park’s inequality方法,结合Lyapunov-Krasovskii泛函处理方法,得到了基于线性矩阵不等式的时滞相关稳定性的新判据;最后,通过实例表明,该方法得到的结论与其他文章相比减少了计算量且结论具有较小的保守性。
