We could see the difference between transfer function and state-space discription.

说明：  在命令窗输入如下内容就得到图形了: [t,x]=ode45( godhua ,[0,10],[0,0,0,1]) subplot(131) plot(t,x(:,4)) xlabel( t ) ylabel( y ) subplot(132) plot(t,x(:,1)) xlabel( t ) ylabel( v ) subplot(133) plot(t,x(:,2)) xlabel( t ) ylabel( \theta ) (At the command window type the following content to be the graphics: [t, x] = ode45 (godhua, [0,10], [0,0,0,1]) subplot (131) plot (t, x (:, 4 )) xlabel (t) ylabel (y) subplot (132) plot (t, x (:, 1)) xlabel (t) ylabel (v) subplot (133) plot (t, x (:, 2)) xlabel ( t) ylabel (heta))

加窗离散傅立叶变换，用DFT对离散信号进行谱分析，通过选用不同的加窗函数来抑制信号截断造成的频谱泄漏(windowed discrete Fourier transform, DFT right discrete signal spectral analysis, the increase in the alternative window function to curb the disconnect signal leakage spectrum)
