This forum is really quite good ~ ~
I have to do is use the 2812 to the direct torque control to control the motor,
by way of the vector look-up table
Now I had a test, according to the requirements of force output on up bridge
followed
011, then output 001, then 101, then 111, then 110, then 010 and finally 110
Correspondence should be under bridge 100 110,010,000,001,101 001
And the timer interrupt has been circulating through the CPU2. But they did not
appear deadband. . .
Ask expert to tell me why,thanks for you help
I did the test procedures are as follows:
EV Time Manager program is as follows:
InitEv(void)
