Within this contribution, attention is focused on a laboratory frame model already investigated in previous papers. It mounts on the top an active mass damper which is driven by two controller: the first uses the feedback of accelerometers to elaborate a driven signal, the second controller drives the engine to follow the path provided by the first controller. The second controller was originally of the analogical type and is now replaced by a digital substitute. The first controller was conceived as wired to the accelerometers, but several wireless solutions for it are proposed. The goal is to assess the performance achieved in different excitation situations.
