It is shown that integration of APPN with ACL cannot obtain much extra damping because of low inverse transmissibility, while the APPN-EACL configuration can achieve high damping around the shunt frequency. The APPN-EACL can be synthesized to outperform the APPN, EACL and APPN-ACL configurations under both narrowband and broadband excitations. The study indicates that while EACL can outperform ACL when the demand on performance is high, it will become less effective than ACL when control effort is very limited. However, with the help of the shunt circuit, APPN-EACL can outperform the APPN-ACL system even when the limitation on control effort is high. © 1997 American Society of Mechanical Engineers (ASME).
