采用改进的直接法在matlab中进行功率谱密度计算(Calculating the direct method using the improved power spectrum density in matlab)

this is about the matlab coding of any servo motor. the code shows how to calculate transfer function and use siso(single input single output) tool.

劳斯稳定性判据的matlab实现。直接运行M文件，按提示输入特征多项式参数，即可进行系统稳定性判别。(The Routh-Hurwitz stability criterion is a necessary (and frequently sufficient) method to establish the stability of a single-input, single-output (SISO), linear time invariant (LTI) control system. More generally, given a polynomial, some calculations using only the coefficients of that polynomial can lead us to the conclusion that it is not stable. in this program you must give your system coefficents and the Routh-Hurwitz table would be shown )
