以下是MATLAB中实现笛卡尔空间多节点轨迹规划的步骤:
1. 定义起始点和终止点,以及路径上的中间点。
2. 根据起始点、终止点和中间点,计算出每个路径段的长度和方向。
3. 根据路径段的长度和方向,计算出每个路径段的速度和加速度。
4. 根据速度和加速度,生成每个路径段的时间序列。
5. 将每个路径段的时间序列连接起来,得到整个路径的时间序列。
6. 根据整个路径的时间序列,生成笛卡尔空间中的轨迹。
具体实现可以参考以下步骤:
1. 定义起始点、终止点和中间点的坐标,例如:
```matlab
start_point = [0, 0, 0];
end_point = [1, 1, 1];
mid_point = [0.5, 0.5, 0.5];
```
2. 计算出每个路径段的长度和方向,例如:
```matlab
path1_length = norm(mid_point - start_point);
path1_direction = (mid_point - start_point) / path1_length;
path2_length = norm(end_point - mid_point);
path2_direction = (end_point - mid_point) / path2_length;
```
3. 根据路径段的长度和方向,计算出每个路径段的速度和加速度,例如:
```matlab
v_max = 1;
a_max = 1.5;
j_max = 10;
[path1_v, path1_a] = s_curve_velocity_profile(path1_length, v_max, a_max, j_max);
[path2_v, path2_a] = s_curve_velocity_profile(path2_length, v_max, a_max, j_max);
```
4. 根据速度和加速度,生成每个路径段的时间序列,例如:
```matlab
path1_t = s_curve_time_profile(path1_length, path1_v, path1_a, j_max);
path2_t = s_curve_time_profile(path2_length, path2_v, path2_a, j_max);
```
5. 将每个路径段的时间序列连接起来,得到整个路径的时间序列,例如:
```matlab
t_total = [path1_t, path1_t(end) + path2_t];
```
6. 根据整个路径的时间序列,生成笛卡尔空间中的轨迹,例如:
```matlab
path1 = path1_direction' * cumtrapz(path1_t, path1_v);
path2 = mid_point' + path2_direction' * cumtrapz(path2_t, path2_v);
path = [path1, path2];
```
其中,s_curve_velocity_profile和s_curve_time_profile是根据S型曲线加减速插补算法计算速度和时间序列的函数。具体实现可以参考引用中的代码。
