摘要 研究多种群非线性竞争反馈控制模型.通过技巧性地引入一个变换,将所研究系统的概周期解存在性问题转化为新系统的概周期解的存在性问题.然后利用微分方程不等式,并通过构造适当的Lyapunov函数,获得该模型有全局吸引的概周期正解的充分条件. n-species nonlinear competitive Lyapunov function, sufficient conditions are system with feedback controls obtained to guarantee the global is proposed. By constructing suitable attractability of the system.
