Patent number: 10308354Abstract: 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.Type: GrantFiled: February 3, 2012Date of Patent: June 4, 2019Assignee: LORD CorporationInventors: Paul Black, Doug Swanson, Askari Badre-Alam, David Edeal, Douglas Pedersen
