为了探索将非线性随机振动系统远离平凡平衡点的状态转移至平凡平衡点的手段,引入了一种模型预测路径积分控制方法。在特定条件下通过指数变换,非线性随机振动最优控制的哈密顿-雅可比-贝尔曼方程可以进行线性化。基于费曼-卡茨定理,可以采用路径积分方法求解最优控制力。引入模型预测控制的思想,可以根据系统实际状态实时更新控制力。针对随机扰动下范德波尔方程和三势阱达芬方程这两类典型系统的控制开展了数值仿真。仿真结果表明,系统状态可以很快地转移至平凡平衡点附近,控制力和即时成本在初始的波动后即转为单调下降。因此,该模型预测控制路径积分方法可以很好地应用于随机非线性系统远离平凡平衡点的振动。

针对基于双马赫-曾德尔干涉的分布式光纤扰动传感系统对传感光信号的偏振状态需要进行实时监测以便及时进行偏振控制的问题,本文提出一种基于支持向量机(SVM)的偏振状态快速判别算法。该方法对采集到的两路干涉信号进行做差处理,得到原始数据。提取原始数据中的过零率与峰值的绝对和作为分类器的输入特征向量,使用Verilog HDL语言编写支持向量机(SVM)分类识别算法,借助现场可编程门阵列(FPGA)的硬件并行结构和流水线技术实现分类器权系数的快速迭代求解。通过提取未知偏振状态信号的特征向量,并将其输入到训练好的支持向量机模型中可以实现高效率的偏振状态识别。实验结果表明:本方法可以快速并准确的实现对系统偏振状态的识别判断,平均识别率达到93.2.%,分类模型训练时间在100 ms以内,平均识别响应时间在8 ms以内。

传统板块构造理论50多年来一直是占统治地位的地学理论,是理解固体地球运行的基本范式,但遇到三大难题:板块起源、板内变形和板块驱动力。针对这三大难题,微板块构造理论试图开拓一个全球构造研究的新范式。本文通过与传统板块构造理论中基本原理的逐条对比,阐明了微板块构造理论的基本原理和优势及其对传统板块构造理论的拓展。微板块构造范式既不同于传统板块构造范式,又不同于地幔柱范式,是两者的重要补充与拓展。文中着重从几何学、运动学、动力学、适用范围、理论出发点、理论假设与预测的角度,阐明了大板块与微板块的异同,并探讨了两者的转换关系及其转换机制的多样性,介绍了微板块生长成为大板块的4种途径、大板块破碎为微板块的3种转换模式,探索了前板块构造体制下微地块在非线性地球系统中通过自组织、自生长等方式,进化为板块体制下微板块的自然选择过程。本文还提出陆壳型微地块是密度选择的结果,其密度决定了其保存机制,这是陆壳起源的根本;微地块向微板块的转变是刚性选择的结果,其刚性是初始板块构造体制起始的必要条件;微板块不对称俯冲或对流型式的转变是热选择的结果,其热不对称性是现代板块构造体制起始的必要条件。
