Computer-integrated drive control in systems with variable imbalance

The paper introduces a computer-integrated system designed for the automatic control in centrifuges with variable imbalance. The system comprises a microcontroller, a Hall sensor, a computer-oriented Bond Graph model of an asynchronous motor, and a control program. The control program utilizes a proposed algorithm to monitor the nominal and critical values of the centrifuge drive current while continuously recording and observing the current. If there is an increase in the current, the system automatically resets the revolutions by 10%, aiming to minimize vibration amplitude during transient rotational modes. Subsequently, the system oversees the permissible current limit and engine load to ensure stable operation.
