Hello all,
I would like to create a model and find inverter losses for the Inner Permanent Magnet Synchronous Motor with Direct Torque Control. I created a model and added it as an attachment. I used the WLTP cycle as a speed reference. I put the parameters from the IPMSM of the Toyota Prius.
First I tried to use the demo model, which is “induction_machine_drive_controlled_with_dtc”, but it didn’t work for PMSM. RPM went to the negative area. You can find it as “Direct Torque Control” block in my model, which I shared as an attachment.
Second I found a schematic from the MATLAB website and tried to model it. You can find it as “Direct Torque Control_1” block in my model, which I shared as an attachment. At that point, RPM went to the positive area but didn’t follow the speed reference.
Matlab schematic link is: Direct Torque Control (DTC) - MATLAB & Simulink - MathWorks Benelux
If you give “0” to a constant value it will work with “Direct Torque Control_1” block.
If you give “1” to a constant value it will work with “Direct Torque Control” block.
Could you please help me to fix the model to follow the given speed reference?
