ON SPATIAL TRAJECTORY PLANNING & OPEN-LOOP CONTROL FOR UNDERACTUATED AUVs
نویسندگان
چکیده
This paper considers the problem of spatial planning and open-loop control for underactuated AUVs. Given a smooth inertial 3D trajectory to be followed by some vehicle point, the developed algorithm uses the vehicle dynamic model, and computes the 3D corresponding body-fixed linear and angular velocities as well as vehicle orientations, yielding a feasible 6 DOF trajectory. Tracking controllers are then facilitated by utilizing this trajectory which is consistent with AUV dynamics. The full 6 DOF computed trajectory is further used to compute the efforts for the three available control inputs and to result in an open-loop trajectory controller. Copyright © 2006 IFAC

Planar trajectory planning and tracking control design for underactuated AUVs
This paper addresses the combined problem of trajectory planning and tracking control for underactuated autonomous underwater vehicles (AUVs) on the horizontal plane. Given a smooth, inertial, 2D reference trajectory, the planning algorithm uses vehicle dynamics to compute the reference orientation and body-fixed velocities. Using these, the error dynamics are obtained. These are stabilized usi...

متن کاملAn Incremental Stochastic Motion Planning Technique for Autonomous Underwater Vehicles
This paper presents a variant of an incremental stochastic motion planning technique for autonomous underwater vehicles (AUVs) that considers both the algebraic constraints, caused by the environment obstacles, and differential constraints, induced by the vehicle dynamics. The term kinodynamic planning is used to describe this type of motion planning. The majority of AUV path planners tend to a...
