Approximate Reachability for Koopman Systems Using Mixed Monotonicity
IEEE Access, 2022 We present a data-driven method for computing reachable sets for unknown nonlinear dynamical systems using a Koopman operator based approach. We find mixed-monotone decompositions for a class of Koopman lifted dynamics.

Parametric Identification of Nonlinear Fractional Hammerstein Models
Fractal and Fractional, 2019 In this paper, a system identification method for continuous fractional-order Hammerstein models is proposed. A block structured nonlinear system constituting a static nonlinear block followed by a fractional-order linear dynamic system is considered ...

Neuro-Fuzzy Network-Based Reduced-Order Modeling of Transonic Aileron Buzz
Aerospace, 2020 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.

Free-Decay Nonlinear System Identification via Mass-Change Scheme
Shock and Vibration, 2019 Methods for nonlinear system identification of structures generally require input-output measured data to estimate the nonlinear model, as a consequence of the noninvariance of the FRFs in nonlinear systems.

Identification of nonlinear systems with stable oscillations [PDF]
IEEE Conference on Decision and Control and European Control Conference, 2011 We propose a convex optimization procedure for identification of nonlinear systems that exhibit stable limit cycles. It extends the “robust identification error” framework in which a convex upper bound on simulation error is optimized to fit rational polynomial models with a strong stability guarantee.

System Identification of a Nonlinear Multivariable Steam Generator Power Plant Using Time Delay and Wavelet Neural Networks [PDF]
Journal of Intelligent Procedures in Electrical Technology, 2013 One of the most effective strategies for steam generator efficiency enhancement is to improve the control system. For such an improvement, it is essential to have an accurate model for the steam generator of power plant.
