Adaptive adjustment of the relationship between the welding process parameters and the butt geometry permits to reduce the likelihood of welding defects appearance and improve the quality of the welded joint in automatic welding of large-diameter pipes. To obtain data on the configuration of the welded joint, the RF627 laser vision sensor is used. To reduce the influence of restrictions arising during the welding process, a median algorithm for filtering impulse noise is proposed. To calculate the geometric parameters of the welded joint, a model based on pixel data obtained from a laser sensor is proposed. The restoration of the welded butt parameters is carried out according to the algorithm of piecewise-linear approximation, which involves the determination of six characteristic points of the butt. The adaptive adjuster uses an inverse neural network model for adjustment the parameters of the welding process: welding current, voltage, wire feed speed. To train the neural network, the characteristic parameters of the welded butt are used: gap, skewing (warping of the edges) and bluntness (for the root weld), the current width of the butt groove in each layer (for other types of welds). The weights of the neural network layers are restored online using a gradient descent algorithm. The important role of the laser vision sensor in solving the problem of adaptation of welding equipment and the effectiveness of the proposed algorithms are confirmed experimentally. Keywords laser vision sensor; robotic welding; multilayer/multi-pass welding; piecewise linear approximation; adaptive control with a reverse neural network model

The process of landing a spacecraft on Mars or another planet is studied. During the descent of the aircraft in the atmosphere, a test mathematical model of guidance is chosen. The criterion of the controllability degree is applied to determine the degree of controllability when moving along various trajectories. Mathematical modeling of the spacecraft guidance process during descent in the Martian atmosphere according to tracking scheme of the program trajectory by using a control algorithm with active disturbance compensation and a proportionalintegralderivative (PID) adjuster is considered. Based on the results of the simulation, it is possible to evaluate and compare the optimality of various reference trajectories by using a criterion that is used as an indicator to study the influence of trajectory parameters on the landing process from the point of view of controllability. Keywords spacecraft, degree of controllability criterion, linear non-stationary system, reference trajectory guidance, control with active disturbance compensation
