...- and closed-loop performance with single harmonic hybrid controller: (a) time domain response at disk 1 and (b) time domain response at disk 2 The work is in progress to implement the proposed research for the rotor dynamic systems with coupling misalignment and rotor bow. UMGF Graduate...

... is entrained at the stability threshold and a stable whirl orbit is observed about the unstable equilibrium. As we move toward the use of more and more lightweight rotor dynamic components such as the shaft and the motor, overlooking this frequency entrainment phenomenon while sizing the actuator in the design...

... storage system rotor dynamics vibration control dc motor actuator H 2 ∕ H ∞ control The suppression of vibration in rotordynamic systems has been a long-standing problem in mechanical engineering ( 1 2 ). These unwanted vibrations can cause increase loading on the system that results...
