获取非线性运动微分方程的poincare截面图和相图(poincare section)

说明：  通过状态空间方法建立了线性二自由度的车辆模型，然后通过转换，将状态空间转换成传递函数的形式，能看到速度变化后，质心侧偏角和横摆角速度的变化趋势。(The vehicle model with linear two degrees of freedom is established by the state space method, and then the state space is transformed into the form of transfer function through transformation. After the speed changes, the change trend of the sideslip angle and the yaw rate of the center of mass can be seen.)
