“…The shafts may draw energy from motor drives or energy from inertial parts causing instability. Some common examples of such engineering systems could be elastic structures subjected to aerodynamic forces, dissipative forces in couplings, hydrodynamic forces due to bearing supporting the rotor (Mukherjee et al, 1984;Mukherjee et al, 1994;Aurich et al, 2009;Glebov et al, 2005;Glebov et al, 2007). This work is devoted to design a completely novel approach for well-tuned bi-stage 2-degree PID type controller using blends of optimal control in the initial stage and then improvising the controller further using the elements of fractional order (Burrows et al, 1989;Dimitri et al, 2010).…”

“…The issue of redemption of face abrasive tool vibrations becomes more significant in the preparation of surfaces of brittle materials such as inorganic glasses and silicon wafers. Glebov and his co-workers have addressed this issue with practical proposals based on both theoretical and experimental studies (Glebov et al, 2005(Glebov et al, , 2007. However their proposal of the incorporation of mechanical dampers, which essentially increase stationary damping and also a system like mechanical tuned dampers, is applicable to medium or large sized grinders.…”

In this paper the authors have extended their work on active stabilization of rotors with circulatory force arising from linear viscous dissipation in a frame rotating with the rotor to an active stabilization of the rotor with face grinding or abrasive tool tip for surface processing of brittle materials like inorganic glasses or thin strata or wafers of semiconducting materials for production of optoelectronic or integrated circuit devices. The dynamics and stabilization of such systems turned out much more complex than one that was addressed earlier due to the complex nature of dry friction forces. To analyze the dynamical nature of dry friction forces in rotating frames four vector operators are proposed. The operators provide a rational basis for creation of paradigms and algorithms (gain switching scheme) for stabilization. The efficacy of the proposals is established by simulation studies.

Destabilizing effects due to rotating damper's in a gyrating or spinning systems is a very common phenomenon. Rotor's at speed higher than certain threshold values become unstable due to rotating damping forces generated by dissipation in rotor materials, coupling or due to friction in spline's and tool tip's. Presently the current methods are mostly passive and suitable for large or medium size rotor's but not quite applicable for small, mini or micro rotor systems. This paper uses an alternative technique to stabilize rotors of any size and description. The authors propose a piezo electrical type of actuating system for applying damping force to the rotating shaft by implementing a smart embedded coupling which rotates along with the rotor. The stabilization control was implemented by designing a simple state feedback Linear Quadratic Regulator whose gains were determined and applied to the rotor shaft through proposed smart embedded coupling.
