- W2963099209 abstract "Abstract Chemical processes are subject to parametric variation due to, among others things, desired changes in process conditions, instrumentation malfunction or unpredicted disturbances. The outcome of these adversities is plural, the entire system may collapse or the output variables might not be affected at all. Thus, the theoretical analysis of processes prone to nonlinear responses plays a key role in design and operation of chemical plants either for safety or economic purposes. Because of the widespread use in the last couple decades of the differential-algebraic equations (DAE) approach in chemical processes modeling, the development of computational algorithms and tools specifically designed for the analysis of DAE systems becomes necessary, specially for high-index cases. In this work, we present a novel and index-free approach for the nonlinear dynamic analysis of mathematical models based on DAEs. A methodology for the direct detection of Hopf bifurcation points based on an optimization procedure, in which we rewrite the necessary condition for the Hopf bifurcation point occurrence as a constrained optimization problem was developed. In this approach, we do not compute the generalized eigenvalues of the system, but their Hurtwitz determinants using a new algorithm for the computation of characteristic polynomials of matrix pencils based on the La Budde’s method. The resulting optimization problem was solved with a hybrid global optimization technique, coupling particle swarm (PSA) and active-set (ASA) algorithms. The parametric continuation of steady-state branches was conducted with the pseudo arc-length method and the stability analysis based on the spectral theory for linear matrix pencils. As an illustrative example we evaluate the dynamic behavior of a reactive flash drum formulated as an index-2 DAE system. The results show that the proposed methodology can handle DAE systems of high index in a fast and accurate way." @default.
