Here's a possible solution with two PI controllers.

 Dear ixo65

Thanks to your useful answer.

I had designed a program nearly like this, but the differences for my application are as below

1- feedback input is 4-20 mA signal

2-output of the program are digital (Q1 and Q2)

3- when the error is zero (hydraulic in the desired position) output signal must be zero (q1 and q2 =0)

my request is, do you have any suggestion to improve my program to work more efficiently.

Please don't post twice for the same problem.
