Hardware-inthe-Loop Simulation of an Active Heave Compensated Drawworks

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. hardware-in-the-loop (HIL), hoisting rig, programmable logic controller (PLC). I. INTRODUCTION HIL simulation was proposed in the early 1990's as a cost and time saving tool for developing electronic and mechanical components [1]. Since then, the application of this strategy for developing embedded systems has become common in several fields. Recent examples include the development of a control system for automatic steering control for an automobile by H. Jamaluddin [2]. Allegre et al. proposed a novel subway design using super capacitors as the main energy source [3]. An HIL test of this design was conducted for experimental validations. Another work by Rankin and Jiangused HIL testing to verify the functionality of safety control systems within nuclear power plants [4]. The setup of an HIL test usually consists of a PC on which a simulation model of the plant is run on. A physical controller such as a PLC is then interfaced with the PC
