The Study Of Immune Controller And Its Application On Tension System Of H-Section Steel

The article tries to study the performances of immune PID controller andfind a new immune controller by using relational theory in the immunology. Onthe one hand, it tries to improve the performances of PID controller. On theother hand, it tries to find a new way for combination of immune controller andPID controller.If organize, cell and molecule can prevent illness and keep stabilization ofthe organism' inside environment, then its theory or model that applyingcontrol system can keep stabilization of control system too.For designing farther efficacious controller by utilizing immune adjustedlaw, first, the immune PID controller has being designed by utilizing immuneadjusted law. And the simulated study was bought to bear the system that beingcomposed of immune PID controller and two ranks plant or two ranks delayplant. At the same time, the simulated study for the parameter of the controllerwas bought to bear the system that being composed of immune PID controllerand two ranks delay plant.But because mathematical model by the using immune adjusted lawcouldn't precisely reflect the characteristics of immune system, so the controlsystem by the immune adjusted law capably is localization. So there are stillvery large room that utilizing the characteristics of immune system in thedesign of control system. Basing the non-line model of cell immune in thereference literature [1], a new immune controller has been designed. And thesimulated study was bought to bear the system that being composed of newimmune controller and two ranks plant or two ranks delay plant like immunePID controller. At the same time, the simulated study for the parameter of thecontroller was also bought to bear the system that being composed of immunePID controller and two ranks delay plant. And, the immune PID controller andthe new immune PID controller that being composed of new immune controllerand PID controller was bought to bear the tension auto-control of H-sectionsteel. The simulation result shows that the capability of new immune PIDcontroller is better than immune PID controller and PID controller. Thereby theeffect turns up trumps.Although systemic study was carried through in this article for immunePID controller and new immune controller, their still need more intelligentways to adjust and optimize them. Because of the parameters of immune PIDcontroller and new immune controller are more than PID controller.
