以水下机器人动态系统建模问题为背景,提出了基于MATLAB/Simulink与FLUENT协同仿真机制与动态神经网络的水下机器人动态系统协同建模方法.该方法利用在对水下机器人动态行为进行协同仿真过程中在线训练神经网络的方式完成水下机器人流体动力学建模,并以最终训练完成的神经网络及载体6自由度运动方程仿真模块一起构成水下机器人动态系统模型,具有较强工程应用前景.通过与传统建模方法比较,详细论述了协同建模方法的基本原理及其优点,并重点研究了MATLAB/Simulink与FLUENT协同仿真系统的设计方案和实现方法,最后,从水下机器人6自由度运动方程建模、流体动力学建模以及闭环控制系统建模三个方面研究了实现协同建模的具体方法. 相似文献

The paper is about negotiating with issues that discourage innovation. The subject is environmental deterioration, with concern directed at the impediments that keep it from being innovatively resolved. The paper is organized around three issues. (1) The dominant model of environmental concern, called environmental protection, is managed predominantly via command and control approaches. (2) Command and control, by relying on analytical segmentation to subdivide the problem into digestible bits and using formal legislation to direct it, are not up to emerging challenges in the area. (3) More robust models are available but difficult to experiment with due to impediments that discourage change. These impediments are seen in ideals associated with protection, prevention, recycling, and sustainability that tend to do more to sustain harmful practices than to seek beneficial alternatives. Being able to appreciate the underlying restrictions of entropy could help stimulate a more innovative agenda. These issues are tested via a project funded by the EPA entitled ENERGY STAR Homes. 相似文献
