Mustafa:

Here is the code of function emfg. It works fine at Matlab 2012/2013.

function y=emfg(u)
if (u>-180)&&(u<=-120)
y=[-1;0;1];
elseif(u>-120)&&(u<=-60)
y=[0;-1;1];
elseif(u>-60)&&(u<=0)
y=[1;-1;0];
elseif(u>0)&&(u<=60)
y=[1;0;-1];
elseif(u>60)&&(u<=120)
y=[0;1;-1];
elseif(u>120)&&(u<=180)
y=[-1;1;0];
end

Some Matlab version have problems with parameter initialization. Kindly add following parameter in initializing function or work space if you get initialization problem.

Rs=1.77;
Rr=1.34;
Lsl=13.93e-3;
Lrl=12.12e-3;
Lm=369e-3;
p=4;
J=0.025;
Bm=1e-5;

Good effort, think some way to reduce the number of power switches
used. I guess there may be the way to eliminate the four central switches.

19 Apr 2014 Speed Control of Brush-less DC motor This model presents speed control of BLDC motor. Author: Syed Abdul Rahman Kashif SUMEET

hello ,
I am working with a PWM-Duty cycle controlled model of BLDC. I saw your model and I am confused by the way you have modelled it. the input to the BLDC block is supposed to be a 3 phase DC voltage and you have made it with a 2-line DC input.
will you be kind enough to explain me and help me understand the idea behind this model.

thanking you

hi sir
Just wondering, what is the physical parameters for this example that you used?
