Firstly, a
piecewise linear system is constructed through piecewise linearization of the Chinese high-speed train's nonlinear dynamics.
In [12], a research on a
piecewise linear system without damping was made, and the closed-form solution for periodic response was obtained.
For instance, the stability and performance of a
piecewise linear system were discussed by means of the quadratic and piecewise-quadratic Lyapunov functions which could cast as convex optimization problems and linear matrix inequalities (LMI) by Hassibi and Boyd [10].
By using this method, the
piecewise linear system can be transformed into a hybrid logic dynamical system [28, 29].
In practical systems, the
piecewise linear system is an efficient method to approximate nonlinear system.
Consider the
piecewise linear system (86) with u [equivalent to] 0.
have established an approach to generate multiscroll attractors via destabilization of
piecewise linear systems based on Hurwitz matrix.

Thus, results similar to those of our model can be obtained in the study of other continuous
piecewise linear systems.
A closely related work is the stability analysis of
piecewise linear systems by [16] in which piecewise quadratic Lyapunov functions were constructed using convex optimization in terms of linear matrix inequalities (LMIs) as an alternative to a globally quadratic Lyapunov function.
