Hardware - in - the - Loop Simulation of an Active Heave Compensated Drawworks

thefollowing contents represent the systematic approach of setting up and running the hardware-in-the-loop (HIL) simulationfor an active heave compensated (AHC) draw-works as a conceptual horizon of implementing HIL for any plant whereby the model is determined. A Simulation model of the draw-works is executed on a PC to simulate the AHC draw-workswith a physical PLC. The PLC (ET200S) is configured with a controller architecture that regulates the motor angular displacement and velocity through actuation of the servo valves.Furthermore, a graphical user interface is developed for operation of the AHC system. The HIL test allowed tuning of the physical controller in terms of heave stabilization and positioning. The conclusion after the testing is a PLC which is ready for operation without necessitating the use a physical prototype of the process.Furhtermore, a graphical user interface (GUI) is developed for operation of the AHC system.
