摘要：

The output and quality of metal plate and strip are heavily affected by performance of the main drive system of rolling mill. Aim at the characteristics of main drive system of rolling mill, such as uncertain external load disturbance and unmodelled dynamics, the model of main drive system of rolling mill is established, where uncertain external load disturbance and unmodelled dynamics are regarded as one integrated disturbance. Then, using extended states observer (ESO), a new observer is proposed to observe and compensate this integrated disturbance, and a robust controller of speed system of rolling mill is designed based on active disturbance rejection control(ADRC) technology. This controller has very strong robustness not only to external load disturbance, but also to unpredictable plant parameter variations such as inertia of load, resistance of armature. Its effectiveness is verified by the simulated result.
