ABSTRACT:
The total periodically induced vibratory disturbance in a structure having unique structural characteristics is minimized. Actuators are operated in response to complex input signals to produce counteractive forces in the structure. Sensors responsive to the vibrational disturbance and the counteractive forces produce outputs indicative thereof. A processor having an electrical characteristic related to the structural characteristic produces complex outputs for each actuator in response to the sensor inputs. The complex outputs are adjusted by the processor to result in a convergence of the structural response to the minimum vibration in response to the disturbance and the actuator inputs.
