摘要：
In order to suppress the speed fluctuations and vibrations generated during the startup and operation of servo motors，a PI control strategy based on pole configuration was proposed. Firstly，an overall dynamic model of servo motors and flexible load was established based on Kirchhoff’s voltage law and Lagrangian principle，and the transfer function of the system was calculated through Laplace transform. Secondly，by designing the parameters of the controller，the impact of using pole configuration methods with the same amplitude on the control effect was analyzed. Finally，the advantages of this pole configuration method were verified by comparing the traditional Z ‐ N methods and uncontrolled methods. Through numerical simulation and experimental research，the control of angle errors generated during the startup and operation of servo motors is achieved，effectively suppressing the fluctuations of motor speed and ensuring the stability of the system. © 2024 Northeast University.
