Selection of parameters for design of engine, turbofan and turbocompressor consisting of turbofan and turbofan mixed flow

open access: yesPerm National Research Polytechnic University Aerospace Engineering Bulletin
The article considers the features of the selection of the main parameters in the design of turbofan and turbofan-type turbofans, turbofans and turbocompressors of the gas generator in their composition. In addition to the known methods, new methods are proposed for using generalized statistical dependencies, such as the ratio of the diametrical ...

Sliding Mode Control in Aerospace Applications: A Survey

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Deep Reinforcement Learning‐Based Control for Real‐Time Hybrid Simulation of Civil Structures

open access: yesInternational Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Real‐time Hybrid Simulation (RTHS) is a cyber‐physical technique that studies the dynamic behavior of a system by combining physical and numerical components that are coupled through a boundary condition enforcer. In structural engineering, the numerical components are subjected to environmental loads that become dynamic displacements of the ...
