Abstract: This paper describes the development of a computer model of a road simulator, and the use of this model to perform frequency response based controller tuning of the road simulator|s hydraulic actuators. In order for a road simulator to effectively serve as a substitute for road tests, it must be able to accurately reproduce a desired road profile. When the system controller was first tuned using conventional tuning rules, the simulator was unable to meet the desired performance objectives. The computer model was developed so that a more fundamental control analysis could be performed on the system and its components. Ultimately, the model was used to develop a better procedure for determining the appropriate controller gains required to achieve the desired performance goals.
