Line D PID Loop controller

Question 1

For a PID controller, what does the proportional do?

Answer 1

It produces an output value that is proportional to the current error value

Question 2

For a PID controller, what does the derivative do?

Answer 2

It sums the error over time

Question 3

For a PID controller, what does the proportional gain do?

Answer 3

It determines the ratio of output response to the error signal

Question 4

For a PID controller, what does the integral do?

Answer 4

It acts as a brake or dampener on the control effort
