模糊系统建模与控制的神经网络方法 总被引:3,自引:0,他引:3
本文将正在迅速发展中的模糊控制、建模方法与神经网络方法结合起来,提出了模糊系统建模与控制的神经网络方法。这种方法的核心是利用神经网络来实现复杂系统的模糊输入和输出间的模糊映射关系,并利用神经网络来学习并记忆人类控制器的知识和经验性的控制策略。本文给出了详细的模型结构和有关算法,并仿真实现了基于神经网络的模糊系统建模与模糊控制。 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
