Hi,
I want to implement sensorless FOC for two BLDC motors using Simulink. But in addition to that I also need to implement fail safe algorithm. Based on some external sensor input the algorithm logic is written and feed back of current, voltage and temperature of both the motors also should be calculated for fail safe operation. I am very new to this field, Please suggest whether TI C2000 launchpad duel motor for FOC will support my requirement or suggest me any other alternative hardware that will support my model.

I had attached my simulink model workflow as an image file

, where I just want to control the orientation of both the motors with the feedback obtained from the running motor and other external sensor.

Thank you

There is no F28035 launchPad, you must use the F28069 launchPad. You might refer to the following link to get more detailed information. For additional help, please contact MathWorks Technical Support

Thank you for your information. But I am afraid that does not answer my question. My doubt is that,

I made a simulink model using two "Matlab function blocks" which will provide two outputs that represent the rotor positon for two BLDC motors. So in addition to my algorithm there is two Sensorless FOC model interfaced with that output.

My question is will C2000(launchpad) TI Microcontrollers be able to solve this because I saw that when two drivers are interfaced with the launchpad, I cannot use any input or output ports. Also I need to do feedback from the motors to detect any error in the motor. So the number of pins in TI C2000 launchpad looks less to carryout my input and output operation. Please suggest on this!

If there is any other hardware that is supported for my purpose and supported by Matlab simulink please provide some info about that. Also if there is a simulink model for embedded coder for sensorless FOC is available, please provide the link.

Thank you!

HI Rakeshwar,

We ship multiple FOC examples in our C2000 Support Package, did you look at them?
