摘要

Torsional oscillations in electrical drive systems with elastic shafts are a well known problem. In the industrial drive systems, a shaft torsional vibration or oscillation is often generated when a motor and a load are connected with a flexible shaft. Large inertias of the motor and load side and a long shaft create an elastic system. The motor speed is different from the load side and the shaft undergoes large torsional torque. In order to damp the torsional vibration effectively, the application of various feedbacks are necessary. The control structures of electrical drives working in the industry are usually based on linear PI controllers. This paper presents the design, analysis and comparison of the conventional PI-control to control structure using PI supported by various feedbacks for performance improvement of the Industrial drives system.
