forming the transformation matrix

I have two images uploaded,i need to perform transformation matrix given in image

http://imgur.com/kF3pm

and i need a block in simulink as

http://imgur.com/F95lw plesae tell how to perform

Answer 1

[Azzi Abdelmalek]

• The first image represents Park transformation, you can use two Matlab function for Direct and inverse transformation.
• The second shows simulink model containing subsystems, we can't guess what they contain, you can built your own model if you are familiar with simulink

Azzi can you please tell how to build park transformation please

Azzi can u please tell is the following blocks available

PWM VOLTAGE and current controller, single phase transformer

[Azzi Abdelmalek]

Use Matlab function to program

function u=park(ua,ub,uc,tetas)
uq=sqrt(2/3)*(cos(tetas)*ua+cos(tetas-2*pi/3)*ub+cos(tetas-4*pi/3)*uc);
ud=sqrt(2/3)*(-sin(tetas)*ua-sin(tetas-2*pi/3)*ub-sin(tetas-4*pi/3)*uc);
u=[uq ud];

and

function u=parki(ud,uq,tetas)
ua=sqrt(2/3)*(cos(tetas)*ud-sin(tetas)*uq);
ub=sqrt(2/3)*(cos(tetas-2*pi/3)*ud-sin(tetas-2*pi/3)*uq);
uc=sqrt(2/3)*(cos(tetas-4*pi/3)*ud-sin(tetas-4*pi/3)*uq);
u=[ua ub uc];

Azzi i get Undefined function or variable 'ua'.and also plesae help me in this

Azzi can u please tell is the following blocks available

PWM VOLTAGE and current controller, single phase transformer

[Azzi Abdelmalek]

You can get them in simpowersystem toolbox (in simscape).

for the function above, you have to use Matlab function block from simulink/user defined functions

[kash]

Azzi in sympowersystem under Elements i could find only for three phase transformer,where single phase transformer will be,also i could not find for PWM also,can u please specify under which block i have to look at please

[Azzi Abdelmalek]

kash, take your time to explore what is under simpowersystem. in simulink search type pwm.

[kash]

Azzi sorry to disturb i had found controlled PWM voltage already,but is PWM voltage controller are same,and i need for current controller also

[Azzi Abdelmalek]

kash, I think you have some gaps to fill, you can't in few minutes built a controller for your applications, maybe you have, first, to read how pwm works, the different technics used, try to built your own pwm model. After that it will be easy for you to understand how to use availables models in Matlab. I did'nt work with pwm, I can just guide you

Thanks a lot Azzi ,as u said i have posted a new question can u please guide me
