- * Multirotor position controller.
+ * The controller has two loops: P loop for position error and PID loop for velocity error.
+ * Output of velocity controller is thrust vector that splitted to thrust direction
+ * (i.e. rotation matrix for multicopter orientation) and thrust module (i.e. multicopter thrust itself).
+ * Controller doesn't use Euler angles for work, they generated only for more human-friendly control and logging.
