摘　　要：提出采用加速度反馈方案,在无需加大系统带宽的情况下提高系统的动态刚度,从而提高了系统对周期性干扰的抑制能力。仿真结果表明,与传统PID控制相比,采用加速度反馈确实能够较好地抑制系统中的周期性干扰。An acceleration feedback control scheme is presented intending to enhance the ability of the system in resisting periodic disturbances via augmenting the overall dynamic stiffness without requiring higher bandwidths of the velocity and position loops. The simulation results are given against those obtained by classical PID control, to confirm the validity of the proposed control scheme.
