Beginning in the late 1970s and continuing today, the sliding mode control has received plenty of attention due to its insensitivity to disturbances and parameter variations. The well known sliding mode control is a particular type of Variable St

由AR模型参数得到功率谱。AR，MA和ARMA是功率谱估计中最主要的参数模型。AR模型的正则方程是一组线性方程。-The AR model parameters obtained power spectrum. AR, MA and ARMA power spectrum estimation is the most important parameter model. Canonical equations AR model is a set of linear equations.
