摘　　要：为了提高多电机转速的同步性和系统鲁棒性,提出了一种新颖的控制方法,即基于非奇异快速终端滑模控制(Non-singular Fast Terminal Sliding Mode Control,NFTSMC)与改进型偏差耦合控制结构(Improve Deviation Coupling Control,IDCC)相结合的多电机速度同步控制方法(NFTSMC+IDCC)。为了提高多电机系统的控制精度和整体稳定性,引入非奇异快速终端滑模控制算法,从而提升单个电机转速的鲁棒性。对传统的偏差耦合多电机速度同步结构进行改进,仿真结果表明,NFTSMC+IDCC方法下的速度同步总误差为17.58 r/min,多电机同步性上相较于其他两组方法提高了50.5%和29%。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.
