spra588 是介绍 Implementation of a Speed Field Oriented Control of 3-phase PMSM Motor using TMS320F240,里面有一段SVPWM输出的程序,我们现在有个工程是使用这段程序的,用的是TMS320LF2407A。现在想更换成TMS320F28034,如何移植这段程序呢?要注意那些方面呢?求指点!!
motorware软件用到的SVPWM也不一样,
The SVM technique used with InstaSPIN is discussed in the following reference:
Advanced Electric Drives, Analysis, Control and Modeling using Simulink, by Ned Mohan, MNPERE Press, Minneapolis, MN 55414, 2001, ISBN# 0-9715292-0-5
This technique was selected because it seamlessly transitions into the overmodulation region of operation by simply increasing the amplitude of the voltage variables from the Inverse Park Transform. A natural clipping effect occurs which causes the waveforms to change from sinusoidal to trapezoidal.
You can replace the SVM module with a more conventional technique if you desire. But you must then manage the overmodulation yourself.
只能帮你到这里了。
