#83665 - Matrix issues
Responding to: ???'s previous message
space vector modulator for matrix converter drives


Sounds pretty impressive yaar !

Apart from that, I have no clue what it means.

But what I can understand is that you are trying to do some calculations on-line which were earlier loaded as a Look up table in a EPROM. If that is so and you have to generate switching pulses: be forewarned on the timings. I have no idea on your required switching bandwidth - but it cannot be great given the fact that you have to do calculations ( and that too with a 8051!)instead of looking it up from a table and then outputting the pulse. An 8051 is a Master when in comes to control. But talk maths and an 8051 is still trying to pass the primary grade...

As to pasting the output C code from matlab into a compiler like Keil - and expecting it to compile - I would say NO. You will have to manually convert / rearrange the code to match the embedded C's unique demands. There is many a thing that is different from ANSI_C when it comes to 8-bit stuff.

And if you are new to 8051, new to C , and new to switching techniques and want to roll all this for a college project work - you have your handsfull and more !!
