Abstract: In many fields of engineering, applications of modern control have become increasingly important. One of the main benefits of modern control is an ability to design a controller to adjust and/or improve the dynamic properties of a system. This paper describes an application of modem control to design a vibration absorption system for a hospital transportation stretcher. The main objective of this work is to reduce the level of vertical vibration induced by path surface roughness as well as road disturbance by using a semi-active vibration absorption system. Modeled the stretcher with the vibration absorption system as a two-degree-of-freedom system, its equations of motion of the stretcher are derived. Measured by accelerometers mounted on the stretcher, road roughness given as the disturbance to the model is applied to investigate the performance of the designed vibration absorption system. The simulation results of the proposed system are presented and discussed
