Designing a Transfer Function in MATLAB for Servo Motor Control

I'm attempting to use MATLAB to solve an electrical engineering problem dealing with controls...

I'm trying to design a transfer function which will control a servo motor using what is often referred to as the Polynomial Equations Aproach.

The approach uses the Sylvester Matrix E to produce a controller for a transfer function.

M = desired controller
E = Sylvester Matrix
D = Diophantine Value = a(z)A(z) + b(z)B(z)
where
PLant Transfer function = B(z)
------
A(z)
a(z) and b(z) are unique polynomials which you multiply A(z) and B(z) by to get your desired state...

To keep from getting everything congested, I'll not post the code here. It is at the link above. (is there a better way to display the code next time?)

Basically, I've been over the MATLAB code so many times my eyes are bleeding and I still can't figure it out...if anyone could I take a look, I'd appreciate it...

The plant transfer functin is controllable, but I didn't include those lines in the MATLAB code.

Thank you.

sorry, that's suppossed to be
B(z)/A(z) = D

darn formatting...

Thank you for sharing your approach and code for designing a transfer function in MATLAB for servo motor control. It seems like you have put a lot of effort into this problem and are still struggling to get it to work. Here are a few suggestions that may help you with your code:

1. It would be helpful to have more context and details about your specific problem and what you are trying to achieve with the transfer function. This will help others understand your approach and provide more targeted feedback.

2. Instead of posting the code on a separate website, it would be better to include it in your post using the "code" formatting option. This will make it easier for others to read and understand your code.

3. Have you tried running your code step by step and checking the results at each stage? This can help identify where the problem may be occurring and make it easier to troubleshoot.

4. You may also want to consider reaching out to the MATLAB community for help. There are many forums and discussion boards dedicated to MATLAB where you can ask for advice and get support from other users.

Overall, it seems like you have a good understanding of the approach and have put in a lot of effort into your code. I hope these suggestions help you in solving your problem. Good luck!
