摘要：
Exponential stability of equilibria of nonlinear distributed parameter systems is considered. A general framework is set with related assumptions. In particular it is shown how to get local exponential stability of an equilibrium profile for the corresponding nonlinear system based on stability results for the linearized one. For this purpose a weakened concept of Frechet differentiability is required for the nonlinear semigroup generated by the nonlinear model, with links to Al Jamal and Morris (2018). The theoretical results are applied to a nonisothermal axial dispersion tubular reactor model and are illustrated with numerical simulations. (C) 2020 Elsevier Ltd. All rights reserved.
