Nonsmooth Modeling of Vibro-Impacting Euler-Bernoulli Beam
Vyasarayani, Chandrika Prakash; Sandhu, Sukhpreet Singh; McPhee, John (Hindawi, 2012-06-17)A new technique to simulate nonsmooth motions occurring in vibro-impacting continuous systems is proposed. Sticking motions that are encountered during vibro-impact simulation are imposed exactly using a Lagrange multiplier, ... -
Parameter identification in dynamic systems using the homotopy optimization approach
Uchida, Thomas Kenji; Vyasarayani, Chandrika Prakash; McPhee, John; Carvalho, Ashwin (Springer, 2011-12)Identifying the parameters in a mathematical model governed by a system of ordinary differential equations is considered in this work. It is assumed that only partial state measurement is available from experiments, and ... -
Single-shooting homotopy method for parameter identification in dynamical systems
Vyasarayani, Chandrika Prakash; Uchida, Thomas; McPhee, John (American Physical Society, 2012-03-02)An algorithm for identifying parameters in dynamical systems is developed in this work using homotopy transformations and the single-shooting method. The equations governing the dynamics of the mathematical model are ...
