Title: Feedforward actuator controller development using the backward-difference method for real-time hybrid simulation (NEES-2013-1225)

Year Of Curation: 2014

Description: The backward-difference method is proposed as an alternative to discretize an improper continuous time model for use as a feedforward controller in RTHS. This method is flexible in that derivatives of any order can be explicitly calculated such that controllers can be developed for models of any order. Using model-based feedforward control with the backward-difference method, accurate actuator control and stable RTHS are demonstrated using a nine-story steel building model implemented with an MR damper.
