Abstract: This report documents the research study conducted on advanced suspension and control algorithms for U.S. Army ground vehicles. It is extremely important to isolate the vehicle body and its contents from terrain-induced vibrations. This enhancement will provide our Warfighters a less-disruptive environment, enabling them to improve their operational effectiveness. Reduced vibration enabled through a well-designed suspension system with an efficient control algorithm will permit higher vehicle speeds as well as better target-aiming accuracy in theater. Military vehicles with a high center of gravity and large variations in gross weights can greatly benefit by using advanced suspension technologies with active, adaptive preview-sensor-based control algorithms. The objective of this research study is to develop a preview-sensor-based control algorithm that can effectively work with advanced semi-active dampers, such as the magnetorheological fluid damper. This report provides a record of the research findings from this research project on advanced suspension and control algorithms for Army ground vehicles.
