Research continues in exploring active control techniques to calm resonant floor vibrations. In this research, an electromagnetic proof-mass actuator is used to deliver the control force in a single-input/multi-output control strategy. With the intent of improving the stability characteristics and the effectiveness of the SISO controller, the relative actuator mass displacement and the actuator mass velocity are added to the floor velocity output used in prior research by the author. Three separate performance indices are developed and implemented to illustrate their particular usefulness in designing an output feedback scheme for controlling pedestrian induced floor motion. The multi-output scheme has been shown analytically to further reduce steady-state acceleration amplitudes by a factor of 7 over the single-output scheme.
