主要研究离散时间切换系统在容许路径依赖混合驻留时间(AED-IDT)切换下异步l_(2)-l_(∞)滤波器的设计问题.不同于以往的研究结果,提出一种异步转移依赖凸Lyapunov函数,得到了低保守性稳定性判据.所设计Lyapunov函数的创新之处在于其构建不再依赖系统模态,而是依赖当前激活的滤波器模态和刚刚运行结束的滤波器模态.鉴于所设计Lyapunov函数具有凸性质,这为所提出方法提升自由度和灵活性创造了空间.采用转移依赖凸Lyapunov函数和AED-IDT切换策略,能够得到保证滤波误差系统全局一致指数稳定,且具有l_(2)-l_(∞)性能的充分条件.在此基础上,提出异步l_(2)-l_(∞)滤波器的设计方法.最后,通过一个数值实例和一个切换RLC应用电路来验证所得结果的有效性,并经过仿真实验验证了所提出设计方法能够保证更紧的驻留时间界和较小的滤波误差结果.

电磁振动水平是永磁同步电动机的重要评价指标之一,为了有效抑制永磁同步电动机的电磁振动,首先建立了转子永磁体磁动势、定子绕组电流磁动势与定子齿槽相互作用产生的径向电磁力的解析分析模型。然后建立了电机的变参数矢量控制系统的场路耦合联合分析模型,以一台11 kW内置式永磁同步电动机为样机,利用机械阻抗法得到了电机主要低阶电磁力产生的电磁振动噪声频谱,确定了对电机电磁振动起主要作用的低阶电磁力的频率。最后利用遗传-蚁群算法,研究了通过优化电机的定子齿槽参数有效削弱具有上述频率的低阶电磁力,从而有效抑制电机的电磁振动。结果显示,利用所提方法确定的定子齿槽参数能有效抑制电机的电磁振动,并且对电机的运行性能产生的影响较小。

Despite of the relatively rare occurrence of alkaline igneous rocks on Earth, they are the most diverse group of igneous rocks due to variations in their mineral assemblages and geochemical compositions. Alkaline igneous rocks are generally characterized by Si undersaturation, and K-Na(and in some cases C) enrichment. Although there is no unified alkaline igneous rock classification scheme, diagrams such as total alkalis-SiO_(2) or K_(2)O-SiO_(2) can be used to classify alkaline igneous rocks. The origins of silica-saturated alkaline rocks(SiO_(2)>52 wt.%) are relatively complex because multiple episodes of magmatism are often involved, therefore most studies have focused on the origins of silica-undersaturated alkaline *** experimental petrological studies have been conducted in the past few decades. Initially, it was considered that enrichment of trace elements was only achieved by low-degree partial melting of mantle peridotite, but the experimental melts could not reproduce the geochemical composition of natural alkaline igneous rocks. Subsequent studies have focused on carbonate-bearing eclogites that represent the average component of subducted oceanic crust. Although experimental studies indicate that silica-undersaturated and alkali-oversaturated melts can be generated from eclogites, some studies have considered that natural silica-undersaturated alkaline igneous rocks are the result of multi-stage source enrichment by incompatible elements. Low-degree partial melts of the mantle can be emplaced in the lithospheric mantle, forming veins consisting of phlogopite, amphibole, and pyroxene. Melting experiments including these components show that the produced melts better reproduce the naturally occurring silica-undersaturated alkaline magmas. Silica-deficient alkaline igneous rocks occur in various tectonic settings. Those in intraplate and divergent settings(i.e., mainly continental rifts) normally involve contributions from recycled components su
