摘要：

An active disturbance rejection synchronous control is proposed for hydraulic servo position systems on driving side and operating side of a rolling mill to deal with the asynchronous pressing down positions due to uncertainties and inconformity between position systems on both sides. The quality of strip thickness and shape are impaired by the asynchronous hydraulic cylinder displacements on two sides. The dynamical mechanism model of the hydraulic servo synchronous system is built. Considering internal parameters variation and external load force fluctuation existing in the systems on both sides, we design an extended state observer to estimate the total uncertainties and inconformity of the synchronous system, and employ a state error feedback law to compensate the total disturbance actively for eliminating the synchronous error. A simulation is carried out on the hydraulic servo system of an 1850 mm reversible aluminum cold rolling mill, and an experiment is conducted on the hydraulic servo synchronous system of a 400 mm reversible cold strip mill for investigating the active disturbance rejection synchronous control. The results validate the controller ability in keeping the same dynamic response and steady state characteristics of driving side position system with that on the operating side, and demonstrate the improvement on the dynamic performance and the robustness of subsystems.
