基于改进GA优化的水下机器人航向鲁棒控制

基于某型号水下机器人水平面线性化模型,针对水下机器人系统存在的多种不确定因素,工作环境复杂多变的问题,采用混合灵敏度法设计水下机器人航向鲁棒控制器。在设计中,通过罚函数小生境遗传适应度值作为桥梁建立起遗传寻优与混合灵敏度参数之间的关系,构成多目标优化问题寻优加权函数。实验结果表明,所用方法可在保证系统较强鲁棒性的同时,又能兼顾时域指标和混合灵敏度加权函数频域要求,获得综合性能指标最优的鲁棒控制器,控制效果较好。     

The pros and cons of Intelligent Speed Adaptation as a restrictive measure for serious speed offenders

In 2011 in the Netherlands a field operational test was performed to investigate the possibility of using restrictive Intelligent Speed Adaptation (ISA) as a penalty system for serious speed offenders. This paper presents the overall results of the research focusing on the pros and cons of the use of ISA as a restrictive measure for serious speed offenders, and on the preconditions for deployment. The results showed that the ISA systems tested have a huge effect on driver behavior and have the potential to improve road safety by reducing the level of speeding, mean speed, as well as the standard deviation of speed. However, there are also cons: the behavioral change in driving behavior was only temporary. In addition the tested technology proved too easy to override, raised issues of equity, and a substantial back office is required when implementing the system for serious speed offenders.     

模糊罚函数遗传算法在船舶型线扫描图光顺中的应用

采用遗传算法进行优化时,处理约束条件的方法一直是理论发展的重点。文章将模糊理论用于优化中处理约束条件的罚函数方法,提出了一种处理的约束优化问题的模糊罚函数遗传算法,并将这种方法用于船舶型线扫描光栅型线的光顺问题,得到了很好的结果。     

海事行政处罚自由裁量权的控制

行政处罚作为一种最严厉的制裁性行政行为,其自由裁量权若被滥用必将严重影响我国的法制建设。文中对海事行政处罚自由裁量权加以探讨,按照合法与公正的原则,研究如何有效控制自由裁量权的行使,以期有利于海事执法部门正确、及时而有效地执法,切实保障海事相对人的合法权益。
