The paper deals with the application of forced dynamic control strategy in the two-mass resonant system. First, the basic of the forced dynamic control theory in the case of the drive system with elastic coupling is presented. The analytical equations which allow for calculating the control structure parameters are given. The included simulation results confirm the effectives of the proposed control In order to apply the proposed control structure the information about non-measurable states is necessary. So general description of the extended Kalman filter is presented. Simulation results were confirmed experimentally in the laboratory setup
