Computer-integrated system of automatic balance control in centrifuge rotors with variable imbalance

The paper presents the developed computer-integrated system of automatic control of rotors balancing in centrifuges with variable imbalance. It includes a microcontroller, a Hall sensor, a computer-oriented Bond Graph model of an asynchronous motor, and a control program that, according to the proposed algorithm, checks the nominal and critical value of the centrifuge drive current. At the same time, the current values are recorded and the current is monitored. When the current increases, the system automatically resets the revolutions by 10% to reduce the amplitude of vibrations in the transient modes of their rotation with further control of the permissible current limit and engine load.
