000022021 520__ $$2eng$$aThe mitigation of the structural response under seismic action can be achieved , as well known, by introducing proper variations to the mechanical parameters of the structural system through the recourse to dynamic control strategies. In order to pursue some optimality in the setup of the problem, sometimes it is necessary to tune the coefficients of the motion equation in a measure that might result not compatible with the characteristics of current structural materials, thus pushing towards active control techniques, where the proper selection of the algorithm is of fundamental importance. As concerns the performance of base-isolation (BI) devices in mitigating inertia forces due to intense earthquakes, it strongly depends on the proper calibration of the own frequency of the BI system, that should be designed on the basis of the dynamic characteristics of both the structural system and the expected disturbance. Nevertheless the passive mode may fail, without guaranteeing the real effectiveness of the device. The best improvement would, thus, require a resettlement of the problem and, possibly, the transformation into a more complex coupled system where some active component is allowed in order to refit the system to its optimality when required. In the paper the design of such system is then proposed in order to respond to major requirements about the performance of the control action, with an active component selected in way to yield a powerful and simple approach, which appears particularly effective for mitigation of dynamic earthquake-induced motion.
