This paper presents the design of a model predictive controller (MPC) based on Laguerre functions for vibration control. The controller is tested in a building‐like structure consisting on a three‐story building with a passive vibration absorber. The structure is connected to an electromagnetic shaker, which excites the support of the superstructure, providing forces with a wide range of excitation frequencies, including some resonance frequencies of the structure. The overall controller is a hybrid vibration absorber conformed of (i) an active absorber, that is a predictive vibration control scheme, synthesised to actively attenuate the vibratory system response via (ii) a passive absorber, known as a tuned mass damper (TMD), located over the third story building to reduce the vibrations caused by harmonic forces acting on the base of the structure. The proposed predictive control strategy proves to be effective and efficient, improving system's performance with guaranteed stability and feasibility. Experimental and numerical results are included to illustrate the overall system performance.
