Many phenomenological friction models are used to describe pneumatic cylinders dynamic behavior, including in pre-sliding zone. These models maintain many unknown empirical parameters (maybe 7 or more). Expensive test equipment and special mathematical methods are required to define the parameters of friction model. But the results may vary significantly for one size cylinders of various manufactures. This paper presents the results of determination the Stribeck friction model parameters based on limited experimental data and procedure of vector identification which implemented in the software complex MOVI (Multicriteria Optimization and Vector Identification). Results were obtained for two types of piston seals materials: NBR and PTFE composite. The minimal value of the piston stable speed for single action cylinders with these seals was estimated.

The problem of transporting swaying cargoes on the vessels in the conditions of rough waters. To study the motion of the cargoes and forecast the emergency it is offered to use the vibratory displacement (transportation) theory mainly developed by the native scientists. The model describes the motion of a flat solid body along the vibrating rough surface. The using of the model enables one to define the velocity of the slow motion of the body and its direction either to the symmetry plane of the vessel or to its boards. The last case is related to the center of gravity shift of the vessel, which leads to an increased roll, or even capsizing. The critical roll angle is specified—the angle corresponding to the start and motion of the swaying cargo on board of the vessel. The possibility of using deformable or granular materials has been noted. A possible application to artificial intelligence-based accident prediction models was considered.

© 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.The article is devoted to the problems of movement and control of a six-legged walking spider-robot. The direct and inverse problems of kinematics of a spatial mechanism are solved. The motion of a walking six-legged robot Hexabot (robot “spider”) with possibility of realization of different motions is considered. The task is to increase the speed of the robot's movement from one position to another by reducing the dynamic loads on the robot leg, as well as by choosing a more rational dynamically balanced gait. In solving the first part of the work, at the first stage, one leg is considered separately as an open kinematic system with three degrees of freedom. Equations of direct and inverse kinematics are obtained. The motion of the platform (the “body” of the spider) is not considered in this work.

We consider a solution of the optimal control problem for an adaptive multidirectional mirror antenna. With the Pontryagin maximum principle, we reduce the problem to solving a system of ordinary differential equations. The resulting system can be solved numerically using modern approaches such as the Runge-Kutta methods or hybrid evolutionary algorithms. Estimation of the state vector is performed by the maximum likelihood criterion with solving the generated Fokker-Planck-Kolmogorov stochastic differential equation. In this case, the posterior probability density function is associated with the normalized value of the energy flux density in the aperture of antenna feeders. We determine the ability to suppress interference with an adaptive multidirectional mirror antenna and give an example of solving the control problem.
