Chapter 15. The PID functions 

15-10 

 

The figure 2.11 shows the variation of PV according to the several different reference 

values (b). As shown in the Fig. 2.11, the small reference value produces small 

deviation value, and it makes the control system response be slow. 

In general, control system  is required to be adaptable to various external / internal 

changes. Especially, it should shows a stable transient response with the sudden 

change of the SV to be robust to load disturbances and/or measurement noise.

Integral windup 

 

All devices to be controlled, actuator, has limitation of operation. The motor has speed 

limit, the valve can not flow over the maximum value. When the control system has 

wide PV range, the PV can be over the maximum output value of actuator. At this time, 

the actuator keeps the maximum output regardless the change of PV while the PV is 

over the maximum output value of actuator. It can shorten the lifetime of actuator. 

When the I control action is used, the deviation term is integrated continuously. It 

makes the output of I control action very large, especially when the response 

characteristic of system is slow. 

This situation that the output of actuator is saturated, is called as ‘windup’. It takes a 

long time that the actuator returns to normal operating state after the windup was 

occurred.
