倒立摆模型的局部线性化
设倒立摆的摆角范围为[-15,15]度,摆角角速度范围为[-200,200]度/秒,摆角角加速度范围为[-200,200]度/秒2,采用三角形隶属函数对摆角和摆角角速度进行模糊化,摆角初始状态为[0.2,0]。 (Inverted pendulum model of the local linear-based inverted pendulum swinging angle of the range of [-15,15] degrees angle angular range of [-200,200] degrees/sec, angular acceleration angle range of [-200,200] degrees/sec 2, the use of triangular membership function of the pendulum angle and angular velocity fuzzy angles, and angles for the initial state [0.2,0].)
