BELTRAN-CARBAJAL, Francisco. Robust tracking control for linear vibrating mechanical systems. Rev.fac.ing.univ. Antioquia [online]. 2015, n.75, pp.211-222. ISSN 0120-6230.  https://doi.org/10.17533/udea.redin.n75a20.

A novel output feedback tracking control approach is proposed for underactuated linear mass-spring-damper vibrating mechanical systems of multiple degrees of freedom. The presented control design methodology considers robustness against unmodeled dynamics and external forces. The proposed control scheme only requires measurements of the position output variable. Tracking error integral compensation is properly used to avoid real-time disturbance estimation. Analytical and numerical results prove the effectiveness of the introduced active vibration control scheme for resonant and chaotic vibration attenuation on the output variable response.

Keywords : mechanical vibration systems; mass-spring-damper systems; multiple degrees-of-freedom mechanical systems; active vibration control.
