Welch法:Welch法对Bartlett法进行了两方面的修正:一是选择适当的窗函数w(n),并在周期图计算前直接加进去,加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠,这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

PID-SIMULATION
控制规律的选用要根据过程特性和工艺要求来选取,决不是说PID控制规律在任何情况下都具有较好的控制性能,不分场合都采用是不明智的。如果这样做,只会给其它工作增加复杂性,并给参数整定带来困难。当采用PID控制器还达不到工艺要求,则需要考虑其它的控制方案。如串级控制、前馈控制、大滞后控制等。
(Choice of control law according to process characteristics and process requirements to select, does not mean that PID control law in any case have a better control performance, are used regardless of where it would be unwise. If you do, will only add to the complexity of other work, and to the parameter tuning difficult. When using the PID controller has not yet reached technological requirements, you need to consider other control options. Such as cascade control, feedforward control, large time delay control.)
