摘要: 交流伺服系统网络化趋势日益显著,针对永磁同步电机的研究主要集中在不断改进的控制策略上,很少与解决实际网络时延和丢包等问题相结合。研究了永磁同步电机(PMSM)矢量控制策略,针对网络环境下存在的时延和丢包,推导出网络控制系统(NCS)数学模型;建立基于TrueTime和Simulink的仿真模型,模拟系统网络传输时的时延和丢包现象结果表明时延使系统超调增大、调节时间加长,PI调节器对其影响有一定的鲁棒性,丢包导致系统稳定性变差。

关键词: 交流伺服系统, 永磁同步电机, TrueTime, 网络时延, 网络丢包

Abstract: The networking trend of AC servo system is becoming more and more remarkable. The research on permanent magnet synchronous motor(PMSM) mainly focuses on the continuous improvement of control strategy. It is rarely combined with solving real network delay and packet loss problems. The vector control strategy of PMSM is studied. In view of the delay and packet loss in the network environment, the mathematical model of network control system (NCS) is derived, and a simulation model based on TrueTime and Simulink is established to simulate the delay and packet loss phenomenon in the network transmission. The results show that the delay increases the overshoot and the adjustment time of the system, and the PI adjuster has some robustness. The packet loss causes the system stability to become worse.

Key words: AC servo system, permanent magnet synchronous motor, TrueTime, network delay, network packet loss
