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.

Rotary wing aircraft vibration control system with resonant inertial actuators

Active vibration control systems () and methods are provided herein. Systems () are expandable and include a plurality of vibration control devices () and at least a first controller () digitally linked with a second controller () via an interface (). The first and the second controllers exchange information for generation of a force control command (FCC) either the first or second controller. The FCC is then executed at a first vibration control device () of the plurality of vibration control devices (FG) for providing active vibration control within a vehicle. A method of providing vibration control in a vehicle includes providing a plurality of active vibration control devices () and providing at least a first controller () digitally linked with a second controller (). The method further includes generating a FCC using information exchanged between the first and the second controllers. The method further includes sending the FCC to a first vibration control device () of the plurality of devices (FG).
