minimum snap trajectory 可以理解为最小化加加加速度轨道 有牛二律深度理解：Jerk: 所受力的变化率。（如每秒增加一牛顿）snap: 所受力的变化率的变化。（如前一秒增加一牛顿，接下来一秒增加两牛顿，第二秒受力与最初相比增加了三牛顿）最小snap，就让jerk变化比较小。如果snap为0，就代表每秒加速...

数学形式上，位置、速度、加速度能直接表示为平坦输出及其导数，姿态角通过引入中间坐标系C，与世界坐标系W的偏航角一致，最终得到四旋翼状态空间变量的表示形式。控制器设计中，轨迹多项式表述形式灵活，不固定每段多项式阶数，但保持相同阶数可简化问题。成本函数考虑起始点、目标点各阶导数约束，中间点位置...
