Vibration Mitigation in Dual-rotor Systems Via Servo Drive Control with Online Mechanical Parameter Identification

This study presents an active vibration control strategy for dual-rotor systems, combining speed tracking and torsional vibration reduction through a servo drive control approach. The method employs an online mechanical parameter identification system to dynamically identify key system parameters such as inertia, stiffness, and damping, thereby enhancing robustness against system parametric variations. To enhance system reliability, a feedback control law and an extended state observer are incorporated within the active disturbance rejection control framework, ensuring precise motor speed regulation, effective vibration mitigation, and real-time parameter adjustment. Simulation studies demonstrate that this method can provide highly accurate real-time parameter identification and superior vibration suppression of a dual-rotor system under varying conditions. The controller's ability to adapt to parametric variations underscores its practical potential in systems where rotor vibration control and operational stability are critical. By integrating real-time identification with an adaptive controller, the developed strategy ensures effective control and robust performance for dual-rotor systems.
