The objective of this study is to find the dynamic characteristics of a hybrid system so that stable performance results near its natural frequency, especially for low mass-ratio structures. Experiments were also conducted on a single degree of freedom rigid frame model and tested for sliding response, as well as its control with the active mass. These results were also compared with the fixed base response of the same model. Significant reduction in response results for the sliding model because of the friction damping characteristics of teflon. A small feedback controlled proof mass further reduced the response. The sliding frame response to harmonic excitation as well as to random excitation, and feedback has been successfully attenuated.
