Hello,
at the moment i am trying to make in simulink an induction motor with vector control. I have a model of an induction motor and the model of the vector control. My problem is the tuning of the PI-controlers for the speeds and for the velocity.
Are there some calculation methods to determine the values?
My interest is especially in the tuning of the two PI-controls for the current. Should the paramter of this controls be calculate successively or at the same time?
Thank you in advance!

Hi Michael,
Assuming that you are not asking about MATLAB automated tuning algorithm, in order to achieve speed control, field-oriented control, and constant flux control simultaneously by Parameter Tuning, a state space model of the induction motor may be required.
Can you provide the state space model?
Dear Mr. Lafifi,
thank you for posting so many publications. Unfortunately some of them dont work.
For me it doesnt matter to tune it with matlab or with a calculate method. The problem with the matlab automated tuning is, i dont know how to simplify the model, especially the SVPWM.
In the literature is described that the current control should be tuned first. My question is, should the iq and id current control be tuned at the same time or should the control of the iq current be tuned first?
My second question is, do i have to use a simulink motor model with friction or can i use an ideal motor model with friction eqaul zero?
Dear Michael,
First concerning links that didn't worked, i think they can normally worked by using only the title and click on it.
Concerning the simplification of model it seems to me that aren't an operation easy and often that can be drive to result badly and especially the SVPWM.
As for the setting of current loops (iq, id, ...) what would be the best strategy to take to obtain the best performance.
-Single setting is the best choice, but it involves more calculation means, more physical and analytical sensors and an implementation accordingly.
-The group control will be of lesser performance and will necessarily impose trade-offs between the parameters to be adjusted as well as the design of the implementation will be lighter.
Finally, the order and priority of the parameters to be controlled is subject to the performance of the final installation.
Hi Michael,
The reason why you are not directed correctly in some links is because those "incorrect" links (with triple dots /.../) are just shortened versions for display purposes. They are not true links. It is a common mistake in forums when some people copy the green "displayed" link as shown in the Google search results. The true link should be copied from the browser address bar. Alternatively, one may conveniently use the "LMGTFY" service. Here you can compare them:

Dear Michael,
I recommend you to check this thesis annex, you will find methods to tune the PI parameters (For both iq & id)
l2ep.univ-lille1.fr/fileupload/file/theses/SalmaElAimani.pdf
Thank you for the literature. I read it, except the thesis, because i can not french.
Unfortunately it doesnt really help me, because i still dont know how to tune the currents PI. Are there some books, which describe it very well? The articles mostly describe the speed regulator.
I dont know, maybe my simulink model is false. The induction motor is in alpha beta coordinates and the vector control is in d-q coordinates. As the PWM i tried to use the SVPWM from this article:

My model:
can you save the model to Matlab 2016a version so i can check it
Dear Ms. Kharchouf,
Here are the model in .slx and .mdl
It would be nice if you would find some mistakes. If you have some suggestions about for example another induction motor model or foc it would be also nice, it doesnt have to be this models.
Thank you very much in advance!
Thank you for your answers!
How can i tune a vector control with a ac motor, which has a changing load?
