Automatic control and measurement of rotating speed of a rotor system
Xiaoxu Yang · 2017
In order to achieve the requirement that the rotating speed of a rotor can be automatically controlled and measured by computer, a new control and measurement scheme based on computer technique is investigated in this paper. The scheme uses an inverter to control the electric motor. And meanwhile, a data acquisition system is used to sample the impulse signal to compute the rotating speed of the rotor. A test experiment, subsequently, is performed on a rotor-bearing rig. Experiment results show that the proposed scheme not only can automatically control the rotating speed of the rotor but also can accurately measuring its real-time speed.
