Research on Lateral Vibration and Load Sensitivity Reductions for Large-Scale Complex Nonconservative Systems Using Rigid-Flex Coupling Simulation Technique

Shock and Vibration
For large-scale complex nonconservative systems such as high-speed rolling stock, the rigid-flex coupling simulation technique is one of the effective methods in reducing lateral vibration and dynamic load sensitivity.

Vibration control for the solar panels of spacecraft: Innovation methods and potential approaches

International Journal of Mechanical System Dynamics, Volume 3, Issue 4, Page 300-330, December 2023., 2023
Abstract Solar panels on spacecraft are typical kinds of flexible structures. Low‐frequency and large‐amplitude vibrations usually occur due to the inevitable disturbances of deployment impact, attitude/orbit maneuver, separation/docking impact, and so forth.

Direction finding by sparse‐based approach for dual‐polarised conformal array in the presence of gain and phase uncertainties

IET Radar, Sonar &Navigation, Volume 17, Issue 6, Page 1040-1049, June 2023., 2023
We investigate the problem of robust direction‐of‐arrival (DOA) estimation with unknown antenna gain and phase uncertainties for the dual‐polarised conformal array. Some techniques including weight sharing, grid pruning, and suppressing the equivalent noise have been adopted to significantly alleviate the negative effects of uncertainties and enhance ...

Feedback stabilization of switched linear systems via a parametric approach

IET Control Theory &Applications, Volume 17, Issue 6, Page 683-695, April 2023., 2023
Two multiple matrix equation problems completely solved in parametric forms. Feedback stabilizaiton for certain linear switched systems under arbitrary switching is realized. Abstract This paper solves two matrix equations problems completely which are originated from the problems of state feedback stabilization of first‐order and second‐order switched

Construction of hybrid 1D‐0D networks for efficient and accurate blood flow simulations

International Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 262-312, February 2023., 2023
A set of coupling equations to appropriately couple nonlinear 1D and lumped‐parameter (0D) models for blood flow in compliant vessels is defined. Then, a methodology for the high‐order numerical coupling between 1D and 0D vessels through hybrid junctions is proposed.

Combined Enhanced LMI Charactrization and Parametric Eigenstructure Assignment Using Static Output Feedback [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2012
This paper proposes mixed eigenstructure assignment with H∞ constraint when the states are not measurable. In this case, full state feedback is not permissible. So eigenstructure assignment by output feedback is considered.

Flight Control Design for a Tailless Aircraft Using Eigenstructure Assignment

International Journal of Aerospace Engineering, 2011
We apply eigenstructure assignment to the design of a flight control system for a wind tunnel model of a tailless aircraft. The aircraft, known as the innovative control effectors (ICEs) aircraft, has unconventional control surfaces plus pitch and yaw ...
