Abstract
A method for stabilizing transversal oscillations of a rotor including the steps of acquiring a first signal representing a value of transversal oscillations of a rotor; estimating a value of a thermal gradient from the first signal; computing a value of an actuation parameter from the value of thermal gradient; emitting an actuation signal representing the value of the actuation parameter.
Claims10
A method for stabilizing transversal oscillations of a rotor, the method comprising the steps of:
- acquiring a first signal representing a value of transversal oscillations of a rotor;
- estimating a value of a thermal gradient from the first signal;
- computing a value of an actuation parameter from the value of thermal gradient;
- emitting an actuation signal representing the value of the actuation parameter;
- and
- actuating at least one weight via an actuator about the rotor to stabilize the transversal oscillations of the rotor.
