pid output zero problem

[belmaalma]

Hello everyone,

I am having problem with my FPGA PID control. When I want to control the speed of motor, the output of PID is always 0. Why is that, and hoce can I fix it. 

I would be grateful for any help.

Are you able to use highlight execution and probes to see where exactly the problem lies? I might check the inputs to the function to make sure you're not getting values of 0 earlier and that the inputs to your PID function are what you expect.
