摘要
针对一类具有功能性反应的捕食与被捕食系统,采用Lyapunov指数方法验证了混沌现象的存在.采用混沌跟踪控制原理设计控制器,控制系统存在的混沌现象使得种群稳定到正不动点轨道和给定周期轨道上,从而消除系统中存在的混沌现象.仿真结果验证了控制器的有效性.
To a class of discrete functional response predator-prey models,the presence of chaos is validated by computing Lyapunov exponent measure method. A controller based on the principle of tracking control of chaos is designed to stabilize chaotic trajectories to unstable fixed points and given period trajectories,and chaotic phenomena in the system are eliminated. Simulation results show the effectiveness of the designed controller.
