摘要
分析了永磁同步电机(PMSM)的数学模型,在此基础上提出了PMSM矢量控制系统仿真建模新方法,在matlab6.5/simlink环境下,建立了速度控制模块、坐标变换模块、SPWM控制模块,并与PMSM本体模块和电压逆变模块有机组合,建立了PMSM控制系统的速度和电流双环仿真模型。仿真实验结果表明该方法有效,也适用于验证其他控制算法,为实际PMSM控制系统的设计和调试提供了新的思路.
In this paper, based on the mathematical model of the permanent-magnet sychronous-motor（PMSM）, a new way of PMSM vector control system model has been taken on. In matlab6.5/simlink, the isolated functional blocks, such as speed controller block, vector controller block, coordinate transform block, SPWM block etc. has been modeled. There are some blocks such as PMSM block, voltage inverter block which are provided by matlab6.5/simlink. By the organic combination of these blocks, a double loop of control system, the speed loop and a current loop are established. The validity has been testified by the simulation results and other control strategies can be applied to the system to testify their rationality. This novel method offers a new thought way for PMSM control system designing and debugging in actual application.
