Which of the following best describe Proportional Integral Derivative (PID) Control?
a) A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how long the input has been away from the setpoint.
b)A system that changes the output of a controller based on the difference between the controlled variable and the setpoint.
c) A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how long the input has been away from the setpoint, and how fast the input is approaching the setpoint.
d)A system that changes the output of a controller based on the difference between the controlled variable and the setpoint, and how fast the rate of change is
