Robust control considering model uncertainty have been widely studied. The benchmark problem using three-inertia system was designed by SICE committee in order to correctly evaluate robust control methods. Traditional robust controller is designed to achieve desired performance for the worst case in a model set. Therefore, it is difficult to achieve high control performance by the traditional robust controller. To overcome this problem, we have proposed a robust control system for this benchmark problem using the model error compensator (MEC) and the frequency shaped final-state control (FFSC). MEC can minimize the gap between real plant and its nominal model. An input signal designed by FFSC can settle desired state variables in terminal period and achieve vibration suppression control. Since MEC is familiar with many other control systems, it is easy to combine FFSC and MEC. Simulation results for the benchmark problem are shown to confirm the effectiveness of proposed method.
