针对峰峰值大范围跳变的稀疏信号的降噪问题,提出了一种全变分后叠加迭代的降噪算法。该算法能够有效地对大范围跳变区间的信号降噪,并保留信号的原始框架。具体而言,进行连续的全变分降噪,对连续降噪后的信号做差,在原信号的基础上对求得的差值进行叠加处理,使其既涵盖了原信号的信息,又保留了之前降噪后的信息。在此基础上再进行迭代,实现对峰峰值大范围跳变的稀疏信号的有效降噪。实验结果与优化最小值算法相比更加接近原始信号。

为了解决高炉多周期装料过程中料面形状变化的问题,设计出一套高炉料面形状控制系统。对于该控制系统,首先,以单容水箱为对象,研究以间歇进水和连续出水为特征的混杂控制问题。然后,在液位位式控制的基础上,将液位混杂系统扩展至用泛函描述的高炉炉料料面形状控制。由于炉料在炉喉径向方向上的实际下降速度存在差异,借鉴非均匀炉料下降模型,并通过仿真实验准确建立出该模型。以多环布料模型、非均匀炉料下降模型和布料矩阵逆计算模型为基础,提出了高炉多周期装料过程中料面形状控制方案,将间歇装料过程与连续下料过程相结合。最终,通过仿真实验实现了料面形状混杂控制,为高炉实际装料过程提供了理论依据。
