Hybrid Quasi-Optimal PID-SDRE Quadrotor Control
Energies, 2022 In the paper, a new cascade control system for an autonomous flight of an unmanned aerial vehicle (UAV) based on Proportional–Integral–Derivative (PID) and finite-time State-Dependent Riccati Equation (SDRE) control is proposed.

Finite-time SDRE control of F16 aircraft dynamics [PDF]
Archives of Control Sciences, 2023 This paper proposes a finite-time horizon suboptimal control strategy based on state-dependent Riccati equation (SDRE) to control of F16 multirole aircraft. Flight stabilizer control of super maneuverable aircraft is modelled and simulated.

Study on maintaining formations during satellite formation flying based on SDRE and LQR
Open Physics, 2017 Due to the influence of various perturbations of space, satellites flying in formation cannot maintain specific configurations for long durations [1, 2]. In order to ensure that formation configurations are able to meet the requirements of space missions,

SDRE-based primary control of DC Microgrids equipped by a fault detection/isolation mechanism
Energy Reports, 2022 Due to the nonlinear dynamics of direct current (DC) microgrids, the existence of input constraints, and their multi-input multi-output (MIMO) nature, classical linear controllers cannot provide an appropriate performance in a wide range of operations ...

Statistical Investigation about the SDRE Optimality for Satellites with Nonlinearities
International Journal of Applied Mathematics, Computational Science and Systems Engineering, 2023 The Attitude Control System (ACS) of a Satellite can be designed with success by linear control theory if the satellite has slow angular motions. However, for fast maneuvers, the linearized models are not able to represent the effects of the nonlinear ...

Study of the regulatory elements of the Ovalbumin gene promoter using CRISPR technology in chicken cells [PDF]
Journal of Biological Engineering, 2023 Background Hormone-dependent promoters are very efficient in transgene expression. Plasmid-based reporter assays have identified regulatory sequences of the Ovalbumin promoter that are involved in response to estrogen and have shown that the deletion of ...
