The Perturbed Compound Poisson Risk Model with Proportional Investment

引用

Acta Mathematicae Applicatae Sinica 2024年第1期40卷 109-128页

作者： Nai-dan Deng chun-wei Wang Jia-en Xu School of Mathematics and Statistics Henan University of Science and TechnologyLuoyang471023China

In this paper, the insurance company considers venture capital and risk-free investment in a constant proportion. The surplus process is perturbed by diffusion. At first, the integro-differential equations satisfied by the expected discounted dividend payments and the Gerber-Shiu function are derived. Then, the approximate solutions of the integro-differential equations are obtained through the sinc method. Finally, the numerical examples are given when the claim sizes follow different distributions. Furthermore, the errors between the explicit solution and the numerical solution are discussed in a special case.

机载雷达组网航迹融合需要解决目标跟踪、数据关联与航迹管理3个子问题,然而这3个子问题相互耦合,采用开环序贯估计算法会导致性能下降.本文提出了一种基于消息传递的机载雷达组网航迹融合方法,该方法在联合优化框架下解决目标跟踪、数据关联与航迹管理3个子问题.首先,建立机载雷达组网航迹融合的联合概率密度函数,并将其转换为因子图.其次,将因子图分解为置信传播区域与平均场近似区域.目标运动状态的统计模型服从共轭指数模型,因此采用平均场近似以获得简单的消息传递更新公式.数据关联包含一对一约束,因此采用置信传播.目标存在状态同样采用置信传播,以获得更好的近似结果.最后,可以通过闭环迭代框架近似估计后验分布,从而有效处理目标跟踪、数据关联与航迹管理之间的耦合问题.仿真结果表明,所提算法的性能优于多假设跟踪算法和联合概率密度关联算法.

针对旋转变压器解码芯片价格高及常规软件解码方法精度不足等问题,提出一种旋转变压器双采样差分位置解码方法。该方法通过主控芯片产生一路方波信号,并对方波信号进行滤波、放大后产生同频率正弦信号作为旋转变压器激励信号。同时,主控芯片在一个激励周期内触发两次模数转换器(ADC)采样,即对旋转变压器输出的正、余弦信号实施双采样。并计算两次采样值的差分,得到与位置相关的正、余弦包络线信号。最后通过锁相环估计转子位置和速度。所提双采样差分位置解码方法可消除正、余弦信号偏置波动对位置估计的影响,且解调信号幅值增大一倍,可提高位置解码精度。实验结果表明,所提双采样差分位置解码方法,相比常规软件解码方法,位置估计精度更高,电机稳态和动态性能更好。
