- 问题是高切滤波或低通滤波,如果采用硬件实现,速度最快,但是现在计算机速度这么快,硬件实现起来相对麻烦,成本高,且灵活性性差, 软件实现相对方便多了,具体体的操作步骤如下(频率域) 先对数据作正FFT,再对变换后的频域数据乘以滤波因子,滤波因子的选择有理想高通、巴特沃斯高通、指数高通、梯形高通,一般选择梯形高通滤波因子,具体原因你可从数字信号处理的书上找到,,接下来将数据再作逆FFT就是了,还有就是在空间域作滤波,这里有一个带同滤波的程序的程序,你可参考一下,(将低切参数设为零就是

- (1)针对在线计算量大这一缺陷,将预测控制中的柔化输出信号的思想推广到柔化输入信号,使得约束条件被简化为仅对当前控制量的约束,可以直接计算得出;同时该方法避免了求逆矩阵,大大减小了计算量,并能够保证控制算法的可行性和良好的控制性能。 (2)针对传统算法中设计参数整定困难这一缺点,应用基于BP神经网络变参数设计的广义预测控制算法,实现了对控制量柔化参数的在线调整。 (3)利用带有遗忘因子的最小二乘法对系统辨识。本文通过仿真发现该方法对于Hénon混沌系统并不完全适用,可考虑利用其他优化系统
