  • Patent number: 10308354
    Abstract: A control system for resonant inertial actuators estimates operating parameters of the resonant inertial actuators based on voltage and current feedback and dynamically limits selected parameters to maintain the safe, efficient, and cost effective operation of the resonant inertial actuators. Resistance within the electrical drives for the resonant inertial actuators is estimated from the voltage and current feedback and in conjunction with the modeling of the resonant inertial actuators other operating parameters are calculated or otherwise estimated. Having regard for the responsiveness of the resonant inertial actuators to changes in command signals, the command signals are adjusted to dynamically limit the estimated parameters.

  • Publication number: 20150370266
    Abstract: Active noise and vibration control (ANVC) systems and methods are provided. The systems and methods include providing sensors configured to detect vibration of a structure and a controller in electrical communication with the sensors. The controller includes a hardware processor and a memory element configured to process the vibration detected by the sensors, generate a force control command signal, and output the force control command signal via an interface. The systems and methods include provisions for at least one circular force generator (CFG) in electrical communication with the controller, the CFG is configured to execute the force control command signal output from the controller and produce a force that substantially cancels the vibration force. In some aspects, one or more CFGs control different vibration frequencies causing unwanted vibrations or acoustical tones. In some aspects, one or more CFG's control unwanted vibrations during some conditions and noise during other conditions.
