摘　　要：从根轨迹的角度研究了金属橡胶件对系统的影响,在合理简化和假设的系统模型基础上,分析了弹性系数对开环零极点分布及稳定域的影响;在双环控制器作用下,研究了弹性系数对闭环系统稳定域的影响。仿真结果表明,弹性系数越小,开环系统的不稳定极点远离虚轴,发散快,相应地,闭环系统的稳定裕度差。The effect of metal rubber damper on maglev system is investigated from the point of view of root locus. The effect of flexibility coefficient on zero-pole placement and stability of open-loop system is analyzed, based on the model right predigested and supposed. With double-loop controller, the effect of flexibility coefficient on stability region of closed-loop system is analyzed. The simulation results show that the smaller flexibility coefficient is, the further the instability-pole-plot of open-loop system is from imaginary axis, correspondingly, the closed-loop system obtains worse stability.
