Hybrid Adaptive Fuzzy Control Based on the Biological Adaptation Strategies

For a class of uncertain nonlinear systems, this paper presents a method based on biological adaptation strategies of hybrid adaptive fuzzy control method. The method in the controller design, the ecological niche theory function as a consequent of the fuzzy rule fuzzy system, is established based on the biological adaptation of the adaptive controller. The controller design embodies the biological adaptability to environment, but also embodies the biological development and utilization of environmental capacity. Through an example, the controller and the controller compared to conventional, has better control effect, but also has good disturbance resistance.
