摘要
研究了新近提出的Liu混沌系统的模糊控制方法。在用T-S模糊模型重构了系统结构的基础上,利用反馈控制思想,设计了Liu混沌系统的模糊控制方法,并通过Lyapunov函数的推导得到了系统以衰减率α全局渐近稳定的充分条件。该方法适用于参数确定的系统和含有不确定参数的系统。文章对两种情况均进行了仿真实验。所有的控制参数可以通过LMI方法得到,仿真结果验证了该控制方法的有效性。该模糊控制方法在连续混沌系统中具有通用性。
The fuzzy control method of a newly-proposed Liu chaotic system is analyzed. Based on the T-S fuzzy model, the Liu system is reconstructed. The fuzzy feedback control method for the Liu chaotic system is designed using feedback control concept. And then the system stability conditions are deduced from Lyapunov function. This method applies to both the systems with certain parameters and the ones with uncertain parameters. Based on the LMI method for both conditions, the results of simulation researches show the effectiveness of the proposed method. This fuzzy feedback control method can be used for continuous chaotic systems.
