“…These attributes have made sliding mode control an appropriate choice to deal with uncertain nonlinear systems similar to the case of the study in this paper. There are also some conducted studies in the literature which have utilized sliding mode control for vibration suppression of 'variable structure systems' by means of intelligent materials (Wang and Kim, 1991;Kim and Wang, 1993;Kim et al, 1999;Li and Wang, 2011).…”

The complex shear modulus of an electrorheological (ER) adaptive sandwich beam is optimally estimated to model the system for vibration control. In the composition of a three layered beam, the ER fluid layer is embedded between two constraining layers. Using finite element (FE) method, the governing equations of the composite viscoelastic beam are derived. The developed model is compared with the results found in the literature. In addition, for a fabricated ER sandwich beam, the ASTM E756 standard is employed to estimate the complex shear modulus of the viscoelastic layer in different electric fields. An optimization procedure is conducted based on particle swarm optimization (PSO). In this process, the rough estimation of complex shear modulus extracted by ASTM E756 is modified to correlate the results of the FE model and the experimental tests. The updated FE model is mapped into an appropriate form that can be used for control objectives. Finally, a semi-active sliding mode control is utilized to attenuate the vibration of the adaptive sandwich beam by tuning its electric field dependent characteristics.

“…The method is insensitive to the spillover problem encountered in fully active systems. The semi-active control law was illustrated on an ER adaptive sandwich beam and simulated to examine theoretical predictions (Wang and Kim, 1991;Kim and Wang, 1993).…”

“…Sliding mode control of an electrorheological fluid damper has also been investigated by several authors [50,53]. In this study, the fluid is modelled with a viscous component related linearly to the applied electric field and a Coulomb component related quadratically to the electric field.…”

“…recognized that the important issue of actuator constraints needs to he addressed to fully utilize the theory. In a recent article (Kim and Wang 1992), the ad-hoc control law is augmented to compensate for the constraint problem. In this present paper, the results of Kim and Wang (1992) are extended to incorporate variable stiffness, viscous damping and Coulomb friction forces (Gandhi et…”
