A State Space Method for Modal Identification of Mechanical Systems from Time Domain Responses
TL;DR: In this paper, a state space method for modal identification of a mechanical system from its time domain impulse or initial condition responses is presented, where the key step is the identification of the characteristic polynomial coefficients of an adjoint system.

Parametric study of loosely coupled INS/GNSS integrity performance
Anja Grosch,Boubeker Belabbas +1 more
TL;DR: It is shown that a network of four independent and identical distributed and orthogonally mounted low-cost sensors boosts the integrity performance significantly and even outperforms the one of a higher grade sensor.
Time Varying Compensator Design for Reconfigurable Structures Using Non-Collocated Feedback
TL;DR: In this paper, a Spline Varying Optimal (SVO) controller is developed for the kinematic nonlinear system, in which the spline function approximates the system model, observer, and controller gain.

Identification of Piezomicropositioning Hammerstein Systems with Generalized Prandtl-Ishlinskii Hysteresis Nonlinearities
TL;DR: An algorithm to identify the nonlinear dynamics of a class of smart micropositioning systems, which is modeled as a Hammerstein system, that is, a cascade of a generalized Prandtl-Ishlinskii hysteresis nonlinearity with a linear dynamic system.
Numerical Stability and Convergence Analysis of Geometric Constraint Enforcement in Dynamic Simulation Systems.
TL;DR: Experiments show that the new implicit constraint enforcement technique demonstrates a superior stability over large time steps and fast system response compared to the explicit Baumgarte method.
