The system above shows a Hybrid system
Hybrid systems are dynamical systems with
interacting continuous-time dynamics and discrete-event dynamics. Hybrid
behavior arises in many contexts, both in man-made systems and in nature.
Continuous systems which have a phased operation, such as walking robots,
insect motion, or biological cell growth and division, are well-suited to be
modeled as hybrid systems, as are continuous systems which are controlled by a
discrete logic, such as achemical plant controlled
with valves and pumps, or the autopilot modes for controlling an aircraft.
Hybrid systems are also natural models for systems comprised of many
interacting subsystems or processes, such as air or ground transportation
systems. “The Art of
