Semi-active control systems provide an attractive solution for the structural control problem. As known, dividing the controller into two components - a damper controller and a system controller simplifies the control law design. The damper controller generates control forces that track some control signal generated by the system controller. A common approach in damper controllers is to use signal clipping whenever the signals generated by the system controller are not realizable due to the physical control limitations. The present study suggests an algorithm for computation of a realizable optimal control feedback, for vibrating structure. The computed control forces are suitable for realization by semi-active dampers controllers without the need for signal clipping. The e ectiveness of the suggested method is demonstrated by numerical example.
