Abstract

In this paper we propose a variational method to find out piecewise‐linear (PWL) approximations of non‐linear dynamical systems in view of their circuit implementations. The method is based on some significant trajectories of the dynamical system and provides reasonably accurate PWL approximations with a relatively low number of parameters. The effectiveness of the method is validated by applying it to the approximation of limit cycles (both stable and unstable) in the Bautin system. Copyright Β© 2006 John Wiley & Sons, Ltd.

This paper proposes a new type of time series model to identify the characteristics of non-linear dynamical structures. The model simultaneously accommodates three kinds of output signals, acceleration, velocity and displacement. This model is more sensitive to non-linearity than models utilising on
