Two kinds of control method

namely immune nonlinearity P and fuzzy self-adjusted integration differentiation ID

have been presented.Combined with advantages of conventional PID controller with that of fuzzy controller and immune feedback control

a new control algorithm called fuzzy adaptive immune nonlinear PID controller has been put forward

so as to overcome the contradiction between rapidity and stability of the system

which is difficult to coordinate using the conventional PID controller

as well as the limitation due to adaptive ability of pure fuzzy control isn't ideal

and being easily to generate oscilation;a fuzzy adaptive immune nonlinear PID controller has been designed

and being used to superheated steam control with features of nonlinearity

time-changing

pure time delay

and uncertainty etc..Results of emulation show that the fuzzy adaptive immune nonlinear PID controller has good dynamic and static performance

faster adaptive behavior

stronger counter-inteference ability and robustness

as compared with the conventional PID controller

and having advantages of betterdynamic tracking performance

smaller over-adjustment

shorter adjusting time

and without oscilation after steady state.
