Inverse Learning Control of Nonlinear Systems Using Support Vector Machines

An inverse learning control scheme using the support vector machine (SVM) for regression was proposed. The inverse learning approach is originally researched in the neural networks. Compared with neural networks, SVMs overcome the problems of local minimum and curse of dimensionality. Additionally, the good generalization performance of SVMs increases the robustness of control system. The method of designing SVM inverse learning controller was presented. The proposed method is demonstrated on tracking problems and the performance is satisfactory.     

杜仲胶工程特性及其在沥青改性中的应用初探

目前国内沥青改性剂大多为石油副产品,造价高且不可再生,无法满足日益增长的公路建设需求,需要找到天然可再生且性能良好、价格适宜的新型改性剂来补充。因此在介绍杜仲胶硫化过程及硫化胶物理力学性能,及其良好的工程学特性及工程应用前景的基础上,根据其具有的橡胶—塑料统一材料谱特点,提出了将天然橡胶——杜仲胶作为改性剂与沥青共混。进行了红外光谱和扫描电镜分析以及沥青基本指标试验,试验结果表明杜仲胶可以改善沥青低温性能、明显改善沥青高温性能,验证了杜仲胶可用于沥青改性的论点。

近场爆炸载荷作用下某大型舰船结构剩余强度分析

近场水下爆炸载荷作用下舰船结构的毁伤效应及剩余强度问题一直是业内研究的重点内容之一。首先,对典型舰船设置近场水下爆炸工况,并结合通用FEM软件对近场爆炸载荷下的结构响应进行模拟。然后,根据近场爆炸产生的破口和塑性变形,对典型剖面剖面模数的损失进行分析,发现由近场爆炸引起的毁伤会导致剖面出现8%~10%的剖面模数的损失。最后,对破损舰船浮力重新分布后的波浪弯矩和静水弯矩进行计算,并结合军规对舰船在近场水下爆炸载荷作用后破损情况下的剩余强度进行分析。结果显示,在鱼雷的攻击下,该型舰船依然满足剩余强度要求。
