摘　　要：振动主动控制主要目的就是利用有效的控制方法达到振动的抑制,尽量减少有害的振动。研究了P型迭代学习控制算法的收敛性,并且针对周期性震动源,探讨了将该算法在振动主动控制中应用。对2-自由度质量弹簧阻尼系统进行仿真实验,结果表明,该算法具有更为良好的性能,特别在低频下,能在较短的时间内使得系统位移为零,达到减震的效果。The main goal of active vibration control is to inhibit vibration by using effective control method, thus decrease harmful vibration. The convergence of P-type iterative learning control algorithm is studied and the application of the algorithm in active vibration control is investigated aiming at periodic vibration sources. The simulation test is conducted to 2-degree of freedom mass spring damping system. The result of the test indicates that the algorithm features good performance,especially under low frequency, the displacement may zero in shorter period to fulfil pur- pose of vibration reduction.
