摘要
针对内埋式永磁同步电动机(IPMSM)给出了d-q轴数学模型,分析了基于空间电压矢量脉宽调制(SVPWM)的IPMSM定子电流最优控制策略.采用最大转矩/电流比(MTPA)和Open-loop Flux-weakening控制算法,给出其参考电流调节器、电流解耦控制器等模块的实现方法,并在Matlab/Simulink环境下构建了基于该控制策略IPMSM调速系统的仿真模型,并在此基础上进行了大量仿真研究.仿真结果表明,电流矢量的波形变化轨迹满足最优定子电流矢量轨迹的变化趋势,系统能够平稳运行,并具有较好的动、静态特性.
With respect to the interior permanent magnet synchronous motor(IPMSM),this paper gives a mathematical model in d-q frame,and based on space voltage vector pulse width modulation(SVPWM) analyzes the stator current optimal control strategy of IPMSM.The maximum torque/current(MTPA) and open-loop flux-weakening control algorithms are adopted.Moreover the implementation method of the reference current regulator and current decoupling controller modules are proposed,on the basis of which a simulation model of IPMSM speed regulation system is constructed in Matlab/Simulink environment,with a large number of simulation experiments having been done.The simulation results indicate that the current vector trajectory can meet the optimal trajectory trend of stator current vector,and the system can run smoothly with good dynamic and static properties.
