A new PD type iterative learning control in active control for vibration
In order to enhance learning efficiency and to deal with the periodic vibration sources, a proposition difference type iterative learning control algorithm is proposed. The PD ILC in the two degree ldquomass spring dampingrdquo mount active solution is vestigated to instead the passive solution. With the method, the performance at low frequencies has been improved specifically. Simulation shows that the displacement could converge to zero fast and that the PD type iterative learning control in active method can achieve vibration isolation excellently.
