代码说明:

采用cross validation的思想可以在某种意义下得到最优的参数,可以有效的避免过学习和欠学习状态的发生,最终对于测试集合的预测得到较理想的准确率.采用实例验证表明,用cross validation选取出的参数来训练SVM得到的模型比随机的选取参数训练SVM得到的模型在最后分类预测上更有效.

下载说明:请别用迅雷下载,失败请重下,重下不扣分!

  • 质量块-阻尼器-弹簧系统的鲁棒控制(论文+程序)
    说明:  用鲁棒控制方法来控制一个简单的二阶机械系统:质量块-阻尼器-弹簧系统。该系统是本科生实验教学中常见的控制实验装置。作为本书中的第一个案例,将针对该装置介绍三种控制器的详细设计方法,分析闭环系统的鲁棒稳定性和鲁棒性能。为了简化设计过程,此处仅考虑模型的结构扰动(参数扰动)。针对此例,介绍了matlab鲁棒控制工具箱(Robust Control Toolbox)一些鲁棒控制器设计指令。希望此章的学习不仅能够教授鲁棒控制系统设计方面的知识,也能够教会大家如何使用鲁棒控制工具箱。(Robust control method is used to control a simple second order mechanical system: mass damper spring system. The system is a common control experimental device in undergraduate experimental teaching. As the first case in this book, the detailed design methods of three controllers for the device are introduced, and the robust stability and robust performance of the closed-loop system are analyzed. In order to simplify the design process, only the structural disturbance (parameter disturbance) of the model is considered here. For this example, some robust controller design instructions of MATLAB robust control toolbox are introduced. I hope that this chapter can not only teach the knowledge of robust control system design, but also teach you how to use robust control toolbox.)
