Underactuated control for an autonomous underwater vehicle with four thrusters by Zainah, Md. Zain

“…The control of Autonomous Underwater Vehicles (AIJVs) is a very challenging task because the model of AUV system has nonlinearities and time-variance,and there are uncertain external disturbances and difficulties in hydrodynamic modeling.The problem of AUV control continues to pose considerable challenges to system designers,especially when the vehicles are underactuated (defined as systems with more degrees-of-freedom(DOFs) than the number of inputs) and exhibit large parameter uncertainties.Hence the dynamical equations of the AUV exhibit so-called second-order nonholonomic constraints,i.e., non-integrable conditions are imposed on the acceleration in one or more DOFs because the AUV lacks capability to command instantaneous accelerations in these directions of the configuration space.Such a nonholonomic system cannot be stabilized by the usual smooth,time-invariant,state feedback control algorithms.From a conceptual standpoint,the problem is quite rich and the tools used to solve it must necessarily be borrowed from solid nonlinear control theory.However,the interest in this type of problem goes well beyond the theoretical aspects because it is well rooted in practical applications that constitute the core of new and exciting underwater mission scenarios.The problem of steering an underactuated AUV to a point with a desired orientation has only recently received special attention in the literature and references therein.This task raises some challenging questions in system control theory because,in addition to being underactuated,the vehicle exhibits complex hydrodynamic effects that must necessarily be taken into account during the controller design phase.Therefore, researchers attempted to design a steering system for the AUV that would rely on its kinematic equations only.In this research, an X4-AUV is modelled as a slender, axisymmetric rigid body whose mass equals the mass of the fluid which it displaces;thus,the vehicle is neutrally buoyant.X4-AUV equipped with four thrusters has 6-DOFs in motion, falls in an underactuated system and also has nonholonomic features.Modelling of ATJV maneuverability first involved the mathematical computation of the rigid body's kinematics,in which roll-pitch-yaw angles in 6-DOFs kinematics are used.We also derive the dynamics model of an X4-AUV with four thrusters using a Lagrange approach, where the modelling includes the consideration of the effect of added mass and inertia.We present a point-to-point control strategy for stabilizing control of an X4-AUV which is not linearly controllable.The goal in point-to-point control is to bring a system from any initial state of the system to a desired state of the system.The construction of stabilizing control for this system is often further complicated by the presence of a drift term in the differential equation describing it dynamically. …”
