Relaxation in Population Dynamics Models with Hysteresis [PDF]
SIAM Journal on Control and Optimization, 2021 The present paper is concerned with a nonlinear partial differential control system subject to a state-dependent and nonconvex control constraint. This system models the dynamics of populations in the vegetation--prey--predator framework and takes account of diffusive and hysteresis effects appearing in the process.

A dynamic model for magnetostrictive hysteresis [PDF]
Proceedings of the 2003 American Control Conference, 2003., 2004 The rate-dependent hysteresis present in thin magnetostrictive actuators can be captured by a dynamic model, consisting of a Preisach operator coupled to an ordinary differential equation in an unusual way. The model presents interesting problems in analysis and computation due to its special structure. In this paper we first transform the model into a
