Comparative analysis of semi-active control algorithms applied to magnetorheological dampers

ABSTRACT This paper analyzes the performance of three different semi-active control algorithms used to calculate and manage the optimal damping forces generated by a pair of magnetorheological (MR) dampers installed in a two-story building. The semi-active algorithms used are the linear quadratic re...
