ROS功能包|mav_control_rw（基于MPC的无人机轨迹跟踪控制）---gazebo仿真测试_ros无人机的真实位置

gazebo仿真测试

启动gazebo并加载无人机模型

$ roslaunch rotors_gazebo mav.launch mav_name:=firefly
1

启动 linear mpc 控制器

$ roslaunch mav_linear_mpc mav_linear_mpc_sim.launch mav_name:=firefly
1

launch启动的节点如下：

<launch>
  <arg name="mav_name" default="firefly" />
  <arg name="namespace" default="$(arg mav_name)"/>
  <group ns="$(arg namespace)">
    <node name="mav_linear_mpc" pkg="mav_linear_mpc" type="mav_linear_mpc_node" respawn="true" clear_params="true" output="screen">
      <remap from="odometry" to="ground_truth/odometry" />
      <rosparam file="$(find mav_linear_mpc)/resources/linear_mpc_$(arg mav_name).yaml" />
      <rosparam file="$(find mav_disturbance_observer)/resources/disturbance_observer_$(arg mav_name).yaml"/>
      <param name="verbose" value="true" />
      <param name="use_rc_teleop" value="false" />
      <param name="reference_frame" value="world" />
    </node>

    <node name="PID_attitude_controller" pkg="mav_lowlevel_attitude_controller" type="mav_pid_attitude_controller_node" respawn="true" clear_params="true" output="screen">
      <remap from="odometry" to="ground_truth/odometry" />
      <rosparam file="$(find mav_lowlevel_attitude_controller)/resources/PID_attitude_$(arg mav_name).yaml" />
    </node>
  </group>
</launch>

启动 rqt
打开Plugins菜单中visualization里的Message Publisher，
在topic的下拉菜单中选择/firefly/command/pose
发布的话题名称为/firefly/command/pose即可实现定点控制拉

更改position 的 x y z 的值，就是给无人机发的位置控制指令

然后勾选那个方框把topic发送出去

无人机运动到了目标位置处

整体的运行效果很理想。
