This paper presents a generalized modeling formulation
for implementation of dynamical system models that exhibit
sliding behavior. The proposed formulation is based
on Filippov theory, and is implemented using Modelica.
The main advantage of the developed framework is that
it effectively removes numerical chattering and trajectory
deadlock. The robustness of the formulation is assessed
considering three example system models: a stick-slip
system, a relay feedback system and an anti-windup Proportional
Integral (PI) controller in a power system application,
i.e. an automatic voltage controller.
Discontinuity, non-smooth, Filippov, hybrid
dynamics, chattering.
