In th.s paper, a novel param.tric m.del-based decom.osition m.th.d is proposed for structural h.alth.m.nitoring of tim.-varying structures. For th.s purpose, th. advanced Functional-Series Tim.-dependent Auto Regressive m.ving Average （FS-TARm.） tech.ique is used to estim.te th. param.ters and innovation variance used in th. param.tric signal decom.osition sch.m.. Additionally, a unique feature extraction and reduction m.th.d based on th. decom.osed signals, known as Latent Com.onents （LCs）, is proposed. To evaluate th. efficiency of th. proposed m.th.d, num.rical sim.lation and an experim.ntal study in th. laboratory were conducted on a tim.-varying structure, wh.re various types of dam.ge were introduced. Th. Fuzzy Expert System.（FES） was used as a classification toot to dem.nstrate th.t th. proposed m.th.d successfully identifies different structural conditions wh.n com.ared with.oth.r m.th.ds based on non-reduced and ordinary feature extraction.

In th.s paper, th. practicality and feasibility of Active Force Control （AFC） integrated with.Fuzzy Logic（AFCAFL） applied to a two link planar arm.actuated by a pair of Pneum.tic Artificial m.scle （PAm. is investigated. Th. study em.h.sizes on th. application and control of PAm.actuators wh.ch.m.y be considered as th. new generation of actuators com.rising fluidic m.scle th.t h.s h.gh.tension force, h.gh.power to weigh. ratio and h.gh.strength.in spite of its drawbacks in th. form.of h.gh.nonlinearity beh.viour, h.gh.h.steresis and tim. varying param.ters. Fuzzy Logic （FL） is used as a tech.ique to estim.te th. best value of th. inertia m.trix of robot arm.essential for th. AFC m.ch.nism.th.t is com.lem.nted with.a conventional Propor- tional-Integral-Derivative （PID） control at th. outerm.st loop. A sim.lation study was first perform.d followed by an experi- m.ntal investigation for validation. Th. experim.ntal study was based on th. independent joint tracking control and coordinated m.tion control of th. arm.in Cartesian or task space. In th. form.r, th. PAm.actuated arm.is com.anded to track th. prescribed trajectories due to h.rm.nic excitations at th. joints for a given frequency, wh.reas for th. latter, two sets of trajectories with.different loadings were considered. A practical rig utilizing a h.rdware-In-Th.-Loop Sim.lation （h.LS） configuration was developed and a num.er of experim.nts were carried out. Th. results of th. experim.nt and th. sim.lation works were in good agreem.nt, wh.ch.verified th. effectiveness and robustness of th. proposed AFCAFL sch.m. actuated by PAm.
