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.
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.
