Grumpy_Mike:
Don't know what you were doing but what ever it was it was not right. A potential divider is a the answer.
Yes, I was wrong. There was connection fault. Potential divider worked perfectly. Thanks for rectifying me.
Have you looked at the signal on a scope? What about the rise time?
No I didn't. I didn't notice the rise time. It would be in milli seconds. I was using induction motors in my project, It has inertia effect , so milliseconds didn't count much. But anyhow my approach was not right.
The major problems are oscillations, instability, problems with minimum current draw and speed of propagation through the regulator.
Yes, these matters much when using for a precision task. Thanks for correcting me.
