摘要
对空间电压矢量(SVPWM)技术和无位置永磁同步电机(PMSM)的位置和速度估计方法进行研究。用基于新一代ARM内核CORTEX-M3的芯片LM3S8971作微控芯片,并结合智能功率模块,设计无位置传感器PMSM矢量控制系统,降低控制器硬件成本和促进新器件的应用。采用MATLAB7.0/Simulink6.5仿真,结果表明系统性能符合设计要求,方案可行。
Using LM3S8971 based on the new ARM Kernel of cortex- m3 as the microcontroller,a controller of sensorless PMSM is. designed with IPM on the basis of research on SVPWM and the position - estimating method of sensorless PMSM in order to reduce hardware cost, promote the usage of new devices. The validity and correctness of the design is verified by simulating with the help of MATLAB 7.0/Simulink 6.5.
