I'm going to implement a motor control based on FPGA with a NIOS II soft processor, I need the system to meet the requirements of TUV and IEC 61508 certificates.
I have read one solution to use a redundancy system, but I couldn't understand how I can do that?
and, does the redundancy system need a physical hardware to be added as an addition with the FPGA? or is there anther soft solution like adding a soft processor such as NIOS II?
 

Hi,

what is the target of the motor control? position, speed, torque, slow, fast...?

What motor? Fuel, stepper, BLDC, brushed DC, asynchronous...?
Motor with or without feedback?

Please divide your task into several smaller tasks.
I recommend:
* specify requirements
* what inputs and outputs do you have?
* select suitable motor
* select suitable motor driver
* choose motor control type
* find FPGA code
* modify code for your need

hi KlausST,

thanks for your replying

I am going to implement a driver for control six permanent magnets synchronous motor (PMSM), using feedback encoder.

regards,
