A kind of improved immune controller

Due to traditional controller´s poor performance in robustness and delay-resistance, many intelligent control methods spring up and artificial immune system is just one of them. In this paper, immune feedback controller is introduced in the aspects of biological principal and controller establishment. It is improved for designing a kind of new immune controller. It is simulated by Matlab Simulink platform. At last it´s applied in the system of DC motor speed control. Simulation research and analysis result demonstrates that the improved controller could yield a better result in terms of dynamic performance, robustness and inference-resistance than the old immune controller or a single fuzzy controller, shedding some light on practical application.
