摘　　要：针对一类不确定非线性系统,设计了一种具有仿生特性的模糊直接自适应控制方法.方法将反应生物特性的生态位态势理论函数作为模糊规则的后件,将生物个体对外界扰动的适应对策引入控制器设计中,利用超稳定理论设计自适应控制律,保证了闭环系统的稳定性和收敛性.仿真结果表明了方法的有效性,比常规控制方法有更好的控制效果.For a class of uncertain nonlinear system, the control method, having the fuzzy direct adaptation based on the bionic characteristic. This method takes the ecological niche theory function reflecting the biology characteristics as a consequent of the fuzzy rule. Leading the biological individuals＇ adaptation strategies to the outside disturbance into the designing of controller, it designs the controlling rule of self-adaptation in the use of Popov, and is sure to keep stability and convergence of the closed-loop system. The simulation result has proved the effectiveness of the method, which has better controlling effects than the conventional controlling methods.
