For this circuit there is a stick connected to a DC motor and potentiometer. The potetiometer can be rotated. I need to control the position of the motor with analaog PID circuit using another potentiometer.
My PID circuit is as below:
The first potentiometer controls the angle. The output potentiometer should give feedback.
I am newbie and this circuit does not work, that means my motor does not work when I supply power.
I checked without the motor connected. There is a voltage and everything is okay but after connecting the motor, the voltage is zero and the system does not work.
Because of the pandemic situation, I cannot use the lab equipment to power supply. I think there is not enough current.
- How can I increase the current?
- How can I make sure the PID circuit is working correctly?
Some information my circuit components:
- All op-amps UA741cp
- Other component same with the designed circuit in picture
- My motor is 820 coreless brushed motor set 3.3V =35000-37000 RPM, 5V = 50000 RPM , Size:8 x 20mm, working current min = 0.15A, weight 6.5gr
