ABSTRACT The article proposes a novel adaptive observer utilising two‐hidden‐layer neural network to estimate the states, including positions, rotations and velocities in North‐East‐Down (NED) reference frame, of Autonomous Underwater Vehicles (AUVs). studied AUVs are characterised by uncertain nonlinear mathematical models, as well effects unknown environmental disturbances. In addition novelty observer's structure, salient feature proposed lies its ability accurately unmeasured states...
The paper proposes a new approach to efficiently control three-dimensional overhead crane with 6 degrees of freedom (DoF). Most the works proposing law for gantry assume that it has five output variables, including three positions trolley, bridge, and pulley two swing angles hoisting cable. In fact, elasticity cable, which causes oscillation in cable direction, is not fully incorporated into model yet. Therefore, our work considers six under-actuated outputs exist system. To design an...
This paper presents a study on behavior of vertical stress profiles in head-enlarged (PF) and conventional CDM columns obtained from field static load test (SLT) numerical analyses. Results the SLT PF installed ideally elastoplastic soil show that, due to configuration column head, plastic failure points happen around at lower levels than that for case column, is showed transfer more pronouncedly column. The distribution – settlement curves analyses instrumented general agree well with...
This paper proposes a novel scheme for stabilization of the 6-DoF Overhead Crane to control movements this system without state measurements through separation principle. The studied in are described more closely than existing crane model when considering six behaviors simultaneously: movement trolley and bridge, two swing angles along x-axis y-axis payload, hoisting drum rotation, axial payload oscillation. mission proposal is make all above 6-DOF be stable accurately enough at desired...
This article proposes a data-driven method for tracking control of the autonomous underwater vehicle (AUV) with matched disturbances and time-varying model's uncertain parameters. The is established by combining conventional model reference principle corresponding procedure step-wise updating controller parameters so that error between AUV an appropriately chosen linear stable converges to zero. update created based on Lagrange interpolation technique, hence it acts entirely experimentally...
This article proposes an approach for output regulation of robotic manipulators without knowing the mathematical model controlled objects, except their degrees freedom. Among this approach, non-linearity, system uncertainties together with input disturbances are totally combined into a lumped component which will be approximated and continuously compensated during operation. A low-pass filter (LPF) is applied to approximate derivation states optimally compensating component. The control...
