“…The above mentioned papers gave us a motivation to see the effects of these non-conservative type forces and its regenerative effects on a very small size pendulum type rotors and see if one can stabilize the rotors without using heavy dampers or squeeze film actuators with even more smart and elegant control strategies. Book chapter [1] MeirovitchL, "Analytical methods in vibration", N.Y Macmillan, and paper [2] was used to see if one can model these dynamical systems using power exchange dynamic graphs namely Bond-graphs which gave much better physical insight to dynamic systems than modeling it with plain differential equations.

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.
