    Study Notes

    Cyber-Physical Systems (CPS)

    • CPS are networked systems where computational and physical elements are tightly integrated.
    • Computational components monitor the system's state, gather environmental information, and provide continuous feedback for control.
    • CPS combine digital and analog devices, interfaces, sensors, networks, actuators, and computers with the natural and built environments.
    • CPS are transforming how humans interact with the physical world, similar to how the internet transformed the way humans interact with information.
    • CPS often include hardware like sensors and actuators, as well as complex software.
    • A key component is the network, which ensures timely information transmission between the physical and computational worlds.
