This paper presents the state-feedback controller design for a three-mass electromechanical system representing elastic overhead crane framework, which allows the suppression of its horizontal vibrations. The design is performed via the pole-placement algorithm ensuring the closed-loop system poles allocation in certain points of complex plane. The simulation results show, that standard polynomial synthesis algorithms for a 2D-controller ensure the optimized behavior of the elastic force applied to the trolley, while the input forces are kept at non-zero constant values during movement with constant speed. In order to improve the system performance two separate reduced-order state-space controllers were designed, each for a fictitious autonomous two-mass system obtained by dividing the trolley mass in reverse proportion to the distance from it to the wheels into two separate bodies, connected to according wheel pairs. The efficiency of such approach was confirmed by means of computer simulation.
