well as the driving conditions.
chapter.
Conditions (or disturbances on our system) can change very rapidly; such as when the car
suddenly encounters a hill. Or may be very slow; such as tire wear reducing efficiency.
PID control can measure and take action on:
The sum of these three evaluations comprises the output drive in an attempt to maintain a
system in equilibrium. Figure 8-1 illustrates the evaluation and control of a system for
PID control.
The classic PID formula for calculating the controller output is as follows:
or
Where:
*(Earlier E was used for Energy. Symbols have multiple uses).
1. How far from the setpoint a system is, or the magnitude of the error.
2. The duration for which an error remains.
3. How quickly an error occurs in the system, or the "rate" of change.
