Hello community,

Is there any example in simulink which uses i2t and T2t Counter to limit overcurrents and torques. I am trying to implement this in my MCU model and it would be really nice if there's some inspiration.

Thanks.

Hi Rohit,

Yes, there are several examples in Simulink that use i2t and T2t counters to limit overcurrents and torques. One of them is the "Induction Motor Control with Field-Oriented Control" example in Simulink also uses an i2t counter to limit the maximum current to protect the motor from overheating.

Here are the references for the better understanding of the same:

Field-Oriented Control of Induction Motor Using Speed Sensor - MATLAB & Simulink Example (mathworks.com)

Field-Oriented Control (FOC) - MATLAB & Simulink (mathworks.com)

I hope the given information helps resolve your query.

Thanks
