In order to improve the synchronization of multi-motor speed and system robustness,the study proposes a novel control method based on Non-singular Fast Terminal Sliding Mode Control with improved Deviation Coupling Control(IDCC)under NFTSMC+IDCC.In order to improve the control accuracy and overall stability of multi-motor system,the study introduces a non-singular fast terminal sliding mode control algorithm to improve the robustness of single motor speed.The traditional variable coupling multi-motor speed synchronization structure is improved.The simulation results show that the total speed synchronization error of the NFTSMC+IDCC method is 17.58 r/min,and the multi-motor synchronization is improved by 50.5%and 29%compared with the other two methods.
