InstaSPIN-FOC for avionic applications

Other Parts Discussed in Thread: TMDSHVMTRINSPIN, CONTROLSUITE, TMDSCNCD28035

Hi,

we are working for an avionic application and we need to certify according to DO-178C all software running in our solution.

We are evaluating InstaSPIN-FOC technology, but we have noticed that the FAST Estimator is available only as ROM library.

Does TI provides something useful to this purpose? For example a certification for FAST Estimator library…

 

Thank you,

Nicola

    Nicola,

    With existing ROM implementation we do not think it is feasible to pass DO-178C certification.

    For next generation silicon with InstaSPIN solutions enabled from ROM we will provide certain processes and documenation for ISO26262 ASIL-B levels. We aren't specifically targetting DO-178, so a judgment would have to be made by the customer as to if they could certify.

    Hi Chris,

    in this case I will have to give up InstaSPIN technology for flight software, probably to use it only for ground applications....


    Using a High Voltage Digital Motor Control Kit (TMDSHVMTRINSPIN), where can I find a sample CCS project that implements the FOC in a traditional way?


    Thank you,

    Nicola

    The HVMTR kit you have can be used with controlSUITE projects

    C:\ti\controlSUITE\development_kits\HVMotorCtrl+PfcKit_v2.1

    for these you will need TMDSCNCD28035 controlCARD for immediate build/run.

    Thanks Chris,

    I am following your indications and I'm analyzing the sensored control example of controlSUITE.

    I guess that's what I need, except that there is still a dependency on the library IQMath: the sources do not seem to be available, and this could still be a problem from the point of view of the certification of the code.

    Does TI provides something useful to this purpose?

     

    Regards,

    Nicola

    We can license you the IQMath source code for soruce code archival (not allowed to change the code)  if required. Have done this for avionics and medical customers in the past.
