Research on Vibration Suppression Method Based on Double Loop Position Feedback Control
Abstract
Aiming at the problem that the position control accuracy of the traditional semi-closed-loop control and the vibration caused by the nonlinear characteristics of the system are easily affected by the full closed-loop control, a double-loop position feedback control based on the state information feedback of the motor and the load is proposed. Based on the double-loop position feedback control framework, a vibration suppression method combining the linear extended state observer, torque feedback compensation and speed feedforward is introduced. The simulation results show that the proposed control method effectively suppresses load vibration, improves the system's servo control performance, and maintains position control accuracy.
