Directing against the problems of the fixed control parameters in traditional PID controller leading to poor control quality
an ideal variation relationship between the error of control parameter and the error of object has been analysed
a non-linear function of the control parameter along with the error variation being given.A non-linear PID controller has been designed on the basis of said non-linear function
and the parameters being set by using NCD module in Simulink.The non-linear PID controller has been used to a main steam temperature control system.The emulation result shows that the non-linear PID controller has better control quality and robustness than that of a conventional PID controller.
