how to design a second order sliding mode control for speed of switched reluctance motor on simulink ?

I am working on a project that deals with high order sliding mode control for speed of a 4 phases switched reluctance motor. I choosed the twisting control method from the high order techniques. I need some help on the design steps on simulink since i have the needed equations.

Thank you in advance

Hi @Mohammed Amin

What are the needed equations?

Hi @Sam Chak

Here are the equations :

Hi @Mohammed Amin,

Thanks for your equations. But I'm unable to comprehend the design methodology. I presume that is the control law and the rest are definitions and the differential equations.

However, you should be able to build the model in Simulink the same way as the block diagram shown in the image.

What specific issue did you encounter when trying to build the blocks in Simulink?

i'm having problem with these two

Thank you @Sam Chak I really appreciate your help.

Can I have your contact sir ? so I can contact you when I need some help; because i still have another part for my project to design a sensorless control using extended Kalman filter.

Thank you .

Hi @Mohammed Amin

I have moved my comment to the Answer section since it helped you to identify the blocks in Simulink. However, I didn't learn about the Extended Kalman Filter (EKF) in my math courses. Is the topic taught in the School of Computer Science?

Feel free to post a new question on the EKF. Please check if there are simple-to-understand examples in the MathWorks documentation where I can self-study and share my knowledge with you.

Hi @Sam Chak I'm struggling with the state space equations. Both EKF and sliding mode deal with state space equations.

Hi @Mohammed Amin

The block in Circle #1 is a Derivative Block, and the block in Circle #2 is the linear State-Space Block. Click on the links for details and examples.
