Let us consider another experimental case, which is one real machine. We are considering some data relative to a rotor rub in turbogenerator operated by an electrical board. In this case the model of the turbogenerator is rather complex. We have a high-pressure turbine, an intermediate pressure turbine, a low-pressure turbine and a generator. There are seven oil film bearings, which support the rotors. In the lower part the values of the rotating speeds, which are used for the identification procedures are shown.
