Abstract
An active vibration control system for reducing vibration of a structure includes a first control loop comprising sensors for sensing forces in a primary vibratory load path and providing signals to a control unit incorporating time domain control logic for providing first actuator demand signals, a second control loop comprising sensors for sensing secondary vibration forces and providing signals to a control unit incorporating frequency domain control logic for providing second actuator demand signals, and a summing device for summing the first and second actuator demand signals and providing resultant signals for operating a plurality of actuators for inputting controlled vibration response forces into the structure to reduce vibration.
