speed regulation loop; how to start from non zero value?

I have a speed regulation loop with the PID and a transfer function. I generated the profile speed input from the "signal builder" and I need to start the loop from the non-zero value. How can I accomplish it?

[Fangjun Jiang]

non-zero value of what, desired speed, controller output, or current speed?

The question is vague but I think this is what you're looking for.

values = [-10 : 10];                         %Here are the negative and positive values you need in the loop

myVariable = nan(size(values));              %allocate loop variable 
for i = 1:length(values)                     %Loop through each value of 'values'
  myVariable = doSomething(values(i));       % Here is your code that references 'values'
end
