how to make simple PID controller using one op-amp? how does look like?

Answer 1

A Proportional Integral Derivative (PID) controller requires no less than 2 operational amplifiers, and generally it would require 3 opamps.
1. Integral - need one opamp to perform integration of input signal.
2. Derivative - need one opamp to perform derivative of input signal.
3. Proportional - need one opamp to provide proportional gain.

If you leave out one of these functions (or set the function gain to zero), it is no longer a PID. It become a PI or PD or simply P controller.

Answer 2

You could do it using passive components.
Straight feedback resistor for proportional.
Add a capacitor/resistor in series for integral.
Add an inductor/resistor in series for differential.
