基于matlab的光纤陀螺磁场作用下零漂测试数据处理程序。
1）读取txt文档中陀螺零漂的实验数据，自动取出有效数据段，并根据一定规律分类
2）作出全部数据图像并保存
3）对各段数据作图，并作平滑处理
4）显示各段数据的最大值、最小值、平均值
5）按周期即序号先后编码文档名称并保存各段数据及图像
6）其他可能的拓展可在本程序基础上修改得到
----------------------------------------------------------------------------
对实验数据的要求：
1）两段有用数据之间间距大于50个记录点
2）有用数据的长度大于100（否则视为无用）
3）本程序目前设置要求人工删去上电时第一点（数据特征呈现为冲击信号），当然也可改变判别变量jg实现-Features: matlab-based fiber-optic gyro magnetic field zero drift test data handler. 1) read txt file in gyro drift experimental data, automatically remove valid data segment, and in accordance with a certain regularity classification 2) to make all the data image and save 3) data for each segment mapping, and for smoothing 4) showing the segment data maximum, minimum, average 5) Press the cycle that has encoded document name and serial number of each piece of data, and save the image 6) Other possible expansion of the program can be modified on the basis of the obtained ---------------------------------------------------------------------------- of the experimental data requirements: 1) between two useful data point spacing is greater than 50 2 records ) useful data length is greater than 100 (or as useless) 3) This program is currently set to require manual deleting the first point on power (data characteristics presented as impact signal), of course, can be changed to ac

Description:
The Z-source converter (ZSC) is a new topology in power conversion, which has unique features that can overcome the limitations of VSI and CSI [5]. Figure 2.1 shows the ZSC implemented as a 3-phase DC/AC converter (inverter). Although DC/AC conversion is the most common application of the Z-source topology, it can also be applied to AC/DC and AC/AC power conversions [24-25]. The X shape impedance is the Z-source network which is composed of two split inductors and two capacitors to provide a coupling between the DC source and the inverter bridge
