English Abstract

The performance of three different feedback control systems has been studied in controlling the vibration of a rotor-bearing system. Two Different mathematical models of the rotor-bearing system have been presented. One model is developed by considering the rotor-bearing system on rigid supports and another model is developed by considering the system on flexible supports. The control techniques applied on these models are: the State variable feedback, Integral plus state variable feedback and Linear quadratic servo. The response of the deflection of the rotor has been simulated on a digital computer. The results of the simulation are presented. These control techniques have been compared on the basis of time-response specifications. The relative suitability of controllers is discussed. The effect of the flexibility of the supports, on the response of the rotor-deflection has been studied. The results obtained for different support stiffnesses are discussed.
