A drawworks is a piece of heavy equipment used in the oil and gas industry for drilling applications. The variable frequency drive (VFD) is used to raise and lower drill string and the top drive during the drilling process. The large inertia of the drill string and top drive lead to challenges in control design to prevent crown-out scenarios that can shutdown a drill site due to damage.
This simulation can be used for actuator sizing, simulation-based control design, and even Hardware-in-the-loop (HIL) simulations. Feel free to add and remove blocks as necessary.
