This paper presents a nonlinear robust adaptive excitation control design procedure for multi machine power systems using back-stepping method. The control objective is to drive machine power angle and frequency to the steady-state operation point, and guarantee that the close-loop system is adaptive to the uncertainties of generator damping coefficient and d-axis reactance, and robust to model errors or bounded disturbances.

利用反步法设计了多机电力系统中的非线性鲁棒自适应励磁控制方案，控制目标是调节发电机功角和频率至稳态运行点的极小领域，并使闭环系统对发电机阻尼系数和电抗参数的不确定性具有自适应能力，且对模型误差和外部有界干扰具备鲁棒性，同时保证各控制器是分散化和本地化的。

In this thesis, the influence of column force, joint hoop reinforcement, and repeat load on the stress and sheer bearing capability of inclined pressure bar is analyzed utilizing finite element software. In the case study, the column axial force's influence on the inclined pressure bar's equivalent width, stress and sheer bearing capability of RCFEN is obtained by changing the column force when modeling the RCFEN with ANSYS. In the former model, the joint hoop reinforcement influence on the equivalent width inclined pressure bar and the strength of RCFEN is achieved by changing the quantity of joint hoop reinforcement; the inclined pressure bar's equivalent width and the strength variation of RCFEN under cyclic load are gained by applying low frequency cyclic load on the inflection point of column and the middle of beam.

It is common knowledge and rather obvious that contemporary art and pop culture have been influencing and mixing up with each other with ever stronger momentum. Generally speaking, such phenomenon is caused by the following factors: first of all, pop culture is an unavoidable existence in the field of the contemporary social culture, especially in urban culture. Elements of pop culture are always employed by artists who attempt to present the modern social life in a critical, ironical or neutral way. But their standpoint and intention of choosing the visual resources are different from that of the mass media and the public.

众所周知，在当代社会中艺术与大众文化的相互渗透、混杂的现象已经明显加剧，造成这种现象的原因大致有这么几点：首先，大众文化是当代社会文化领域，特别是都市文化领域中一个不能回避的问题，不管艺术家是处于批判、反讽或者是不动声色的呈现当代社会生活的时候都涉及到运用大众文化形态的问题，只不过艺术家选择这些视觉资源的时候其出发点及立场与大众传媒和社会公众不同。
