摘要：该文深入研究目标全息反馈非线性控制(nonlinear control with objective holographic feedbacks,NCOHF)设计方法在单输入多输出(single input multiple output,SIMO)控制系统中发挥作用的机理。鉴于线性系统是非线性系统的特例,将NCOHF设计方法用于线性控制系统中。详细讨论NCOHF设计方法配置系统极点的原理和解决目标量跟踪精度的本质。基于Hartman-Grobman定理,得出其非线性控制设计实质,即:通过非线性反馈对非线性控制系统在平衡点附近进行极点配置,通过反馈系数对目标量分别约束,从而迫使目标量收敛于各自的参考轨迹。以发电机励磁控制系统为例,给出应用实例,提出目标全息反馈非线性励磁控制(NECOHF)设计方案。仿真结果表明:通过极点配置进行设计,使得发电机具有良好的输出特性。

摘要：Active fault creep slip induces deformation of rock mass buried deeply in fault zones that significantly affect the operational safety of long linear projects passing through *** distribution patterns of rock masses in active fault zones which have been investigated previously are the key design basis for such ***,a discrete element numerical model with different fault types,slip time,dip angles,and complex geological features was established,and then the creep slip for normal,reverse,and strike-slip faults were simulated to analyze the displacement distribution in the fault rock mass.A disk rotation test system and the corresponding laboratory test method were developed for simulating rock mass displacement induced by creep slippage of faults.A series of rotation tests for softand hard-layered specimens under combined compression and torsional stress were conducted to verify the numerical results and analyze the factors influencing the displacement *** S-shaped displacement distribution independent of fault dip angle was identified corresponding to reverse,normal,and strike-slip *** results indicated that the higher the degree of horizontal extrusion,the softer the rock mass at the fault core,and the higher the degree of displacement concentration in the fault core;about 70%of the creep slip displacement occurs within this zone under 100 years of creep slippage.

摘要：艺术与政治之间究竟存在着何种关系,这种关系又是如何影响艺术的创作与评价的,这个问题一直没有引起研究者的高度关注。文章以品特的经典之作《回家》与《背叛》为例,探讨在审美的伦理与再现领域中,艺术形式如何摆脱表象意识形态的镣铐,在无形的"政治语境"中彰显有形的"文化语境"。在拉康以及德勒兹的理论框架中,通过考察两部经典之作的"能指"与"所指"的运作方式,分析意识形态是如何在艺术与政治之间建构审美判断,进而影响品特艺术的创作思想的。分析的结论是,政治与艺术在它们"不在"的空间被审美意识形态言说着,产生了变异的艺术根茎"他者"。"他者"在不可见的意识形态中成为大众的审美判断,于是,品特艺术在"自我"形式之外的虚无世界中被政治观念所建构。
