Abstract
In this paper, a sliding mode control strategy is proposed to solve the problem of anti-resonance of the flexible load of permanent magnet synchronous transmission system. The sliding mode control method can effectively suppress the resonance and improve the dynamic performance and robustness of the system. In order to achieve this goal, we first analyze the dynamic characteristics of permanent magnet synchronous transmission system and the influence mechanism of flexible load. On this basis, a new sliding mode controller is designed, which combines modern control theory and intelligent algorithm, and can adjust the control strategy according to the system state in real time to achieve effective suppression of resonance. The experimental results show that the designed sliding mode controller performs well in the flexible load control of permanent magnet synchronous transmission system, not only effectively inhibits the resonance phenomenon, but also significantly improves the response speed and steady-state accuracy of the system. In addition, the controller also shows good robustness, and has strong resistance to system parameter changes and external interference.
