Laguerre-Gram Reduced-Order Modeling [PDF]
International audienceWe present an efficient model reduction procedure based on the Laguerre description of the system to be approximated. Using a one-order operator defined in the Laplace domain we construct a pencil of functions and formulate the ...

Neuro-Fuzzy Network-Based Reduced-Order Modeling of Transonic Aileron Buzz
In the present work, a reduced-order modeling (ROM) framework based on a recurrent neuro-fuzzy model (NFM) that is serial connected with a multilayer perceptron (MLP) neural network is applied for the computation of transonic aileron buzz.

Reduced-Order Thermal Modeling for Photovoltaic Inverters Considering Mission Profile Dynamics
Power devices are among the reliability-critical components in the Photovoltaic (PV) inverter, whose failures are normally related to the thermal stress. Therefore, thermal modeling is required for estimating the thermal stress of the power devices under

Reduced-order modeling and dynamics of nonlinear acoustic waves in a combustion chamber [PDF]
For understanding the fundamental properties of unsteady motions in combustion chambers, and for applications of active feedback control, reduced-order models occupy a uniquely important position. A framework exists for transforming the representation of

Reduced Order Modeling of Composite Laminates Through Solid-Shell Coupling
Composite laminates display a complex mechanical behavior due to their microstructure, with a through-thickness variation of the displacement and stress fields that depends on the fiber orientation in each layer. Aiming to develop reduced-order numerical

On the Selection of Tuning Methodology of FOPID Controllers for the Control of Higher Order Processes [PDF]
In this paper, a comparative study is done on the time and frequency domain tuning strategies for fractional order (FO) PID controllers to handle higher order processes. A new fractional order template for reduced parameter modeling of stable minimum/non-

Controlling quantum many-body systems using reduced-order modeling
Quantum many-body control is among the most challenging problems in quantum science due to its outstanding computational complexity in a general case. We propose an efficient approach to a class of many-body quantum control problems, where time-dependent
