The Study on the Hierarchical Identification Method in the Debugging of Turntable Servo System
递阶辨识方法在转台伺服系统调试中的应用研究

In view of the fact that mechanical resonance in the turntable servo system has serious effects on the whole system,this paper adopts hierarchical identification method with fewer quantity of computation to identify the plant containing mechanical resonance. After suppressing the resonance effectively by identification results, dynamic performance of the system has been improved greatly. The method not only overcomes the difficulty of large quantity of computation and storage, but also gets over problems of fussy debug procedure and low precision result proposed by the old method, and as a further result of which, it also improves the automatic debugging standard and the system's performance adequately.
