| Abstract: | According to the definition of the stiffness of electromechanical actuation system,its improvement method was analyzed based on the control theory.The way to improve the stiffness of electromechanical actuation system by dint of notch filter which restrained the resonance in system and the increasing gain of system was presented through the time domain and the frequency domain simulation and the analysis of one electromechanical actuation system.Simulation results show that the resonance in system is restrained efficiently by the notch filter and the gain of system is increased,and the stiffness of system is improved. |
