摘要

摘要: 讨论了参数不确定永磁同步电机固定时间的同步问题. 根据固定时间控制理论和Lyapunov稳定性理论，针对不确定参数的永磁同步电机，设计固定时间同步策略. 根据自适应控制技术和不等式技术，得到固定时间同步控制器，使得参数不确定永磁同步电机能够在较短时间内实现同步，且同步时间的上界只与系统参数有关. 通过仿真和结果比较验证了所提出的固定时间同步策略的有效性．

Abstract: The fixed-time synchronization problem was solved for permanent magnet synchronous motor (PMSM) with parameter uncertainties. Based on the fixed-time control theory and Lyapunov stability theory, the new fixed-time synchronization scheme was designed for PMSM with uncertain parameters. According to the adaptive control method and inequality technique, the fixed-time synchronization controller was obtained, which makes the PMSM with uncertain parameters achieve fixed-time synchronization in a short time, and the upper bound of the synchronization time is only related to the system parameters. The simulation and comparison results confirmed the validity of the proposed results.
