In view of defects existing in conventinal superheated steam temperature control

such as slow response speed

long transient time

and large overshoot magnitude etc.

a design method of the controller based on adaptive regulations has been put forward

making parameters of the PID controller can automatically suit to the variation of object

achieving the purpose of optimal controlling. At the same time

the configuration of adaptive controller and the working principle of its every part have been given. The result of simulation shows that the quality of adaptive PID controller is much better than that of the conventional PID controlling.
