| 摘 要： | 提出一种空间矢量脉宽调制(Space Vector Pulse Width Modulation,简称SVPWM)细分优化算法.采用尽可能多条边的正多边形对磁场圆进行细分,并对细分后的SVPWM脉冲进一步优化,有效消除了窄脉冲.然后通过Matlab 离线计算,并基于DSP-现场可编程门阵列(Field Programmable Gate Array,简称FPGA)实现该算法.交流调速实验表明,该算法不仅易于数字化实现,便于实时控制,而且具有良好的控制效果.

| Abstract: | A subdivision and optimization space vector pulse width modulation(SVPWM)algorithm is proposed.In this method,the flux circle is subdivided into more parts by regular polygon and the SVPWM pulses are further optimized to eliminate narrow pulses.Furthermore,this method is realized based on DSP-FPGA after calculating off-line on Matlab.The AC motors speed-regulating experimental results indicate that the proposed algorithm is easy to realize for digitalization and real-time control,and has a good control perf... |
