Examples
- 2 ) by analyzing the information and conditional information description mechanism of system states , the problem of stochastic model reduction is investigated based on state aggregation . the information loss and conditional information loss between the full - and reduced - order models are measured by entropy , while the independence and conditional independence within me components of aggregated state are measured by kullback - leibler information distance . several model reduction methods for stable and unstable linear systems are derived by employing two criteria to get aggregation matrices : the minimal information loss and the maximal independence
2 )分析了随机系统状态空间模型中的信息和条件信息描述机制，以shannon熵为手段描述线性系统模型降阶过程中的信息和条件信息损失，以kullback - leibler信息作为衡量降阶模型状态向量各分量之间统计独立性的测度，针对稳定和不稳定系统研究基于状态集聚的模型降阶问题：分别运用最小信息损失准则和最大独立性原则，得出几种状态集聚的信息论方法，并讨论降阶模型的性质、阶次的确定、系统噪声分布特性等问题。 - In order to simulating rapidly and analyzing the dynamic behavior of the whole mems but not reducing accuracy significantly , the terminal behavior of multi - terminal components was modeled as reduced - order model ( or called macromodel ) . upon the finite element model theory micro - mechanical devices or components were modeled in the spatial , which afforded theoretic foundation and technical support to mems system - level design
为了便于在不显著影响精度而能快速地仿真与分析mems整个系统动态行为，通过器件或组件的降阶模型(或称为宏模型)方法描述了多端口组件的端口行为，并采用有限元模型理论在三维空间内建立了微机械器件或组件宏模型，为系统级设计所需要的组件库的建立提供了理论基础和技术支持。 - Based on a reduced - order model , the vsc of flexible rotor - magnetic bearing system is also investigated . a master - slave controller composed of a pc586 and a tms320c50 dsp board is build and a flexible rotor - magnetic bearing test rig is developed . simulation and experimental results show that the vsc is insensitive to the spillover problem due to the model truncation and parameter uncertainty
结果表明,变结构控制器对于因模态截断及非并置问题导致的未建模动态以及因系统自身特性变化而导致的参数摄动具有不敏感性,系统在上浮过程、受到外界扰动及复杂运转情况下的性能均优于pid控制器。
