Hi does anyone know what is wrong ? Is there something I need to further clarify ? I have beent trying to tune PI values but nothing has improved. I have tried playing around with the motor and nothing either. I thought it would simple to implement since it's basically linking blocks together. I hope you are just not answering because they genuily don't know the answer but if there is another reason nobody is replying please let me know because I really need to do what I am doing wrong. Thanks.
Non-constant Torque issue in FOC algorithm (Simulink)
2 views (last 30 days)
I am trying to develop an FOC algorithm in Simulink (see image attached) but I am having extrange results in my simulation. My torque is not constant, when it should, but varying periodically (see image attached), when it should be constant at 2 Nm. Also the scope for my q-axis current my probe is giving me a strange graph (see image attached) I can't even make sense of. Please if anyone could help me I would really appreciate it since I have no clue what is going on. I don't know if it could be the values of my PI regulator but I have already tried all sorts of values and have no idea what else I can do. Please could someone help me out ?
P.S. Simulink file attached below.
