由于神经网络技术的发展，神经网络在非线性控制方面显示出强大的优势，同时近年来出现的逆系统方法对于多变量非线性系统的控制指出了一条可算是光明的道路，鉴于以上两项技术的优越性，本文提出对BMPS进行神经网络逆系统控制的方法，首先通过机理分析的方法建立了BMPS的非线性动态数学模型，并依此模型设计了神经网络逆系统控制方案，由于此方案中需要用到球磨机磨筒内负荷的反馈，但是磨内负荷是一个不能直接测量的量，而且其测量方法是多年来人们一直在努力的方向却又一直不能较好地解决，本文提出对其进行神经网络测量的思想和方法，这一方法的仿真试验和现场实测结果均表明其研发造价低廉的优越性和测量较为准确的实用性。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.

针对当前XML数据流质量检测存在的不足，提出构建XML键的矢量矩阵作为窗口，利用矢量积小波变换多级分解与重构XML数据流，再结合最小二乘支持向量机对XML数据流质量进行预测的一种方法，满足XML数据流质量重构时实时检测的要求，保证XML数据的约束性、一致性与完整性；为了更好的适应网络负载，采取加权与自适应窗口调整等调度策略充分保证XML数据流的质量检测。
