针对受扰统一混沌系统,提出一种主动自适应模糊积分滑模控制方法.在保持原非线性积分滑模控制暂态性能的同时,设计了一种改进非线性积分滑模控制方法,保证了系统的稳定性.所提出控制方法减小了统一混沌系统的不可控状态和自适应模糊补偿项的逼近精度对系统状态误差的影响.基于Lyapunov稳定性理论分析了系统的稳定性.数值仿真结果表明,在存在参数摄动和外部扰动时,能将统一混沌系统控制到目标点上.数值仿真验证了所提出控制方法的有效性.
Aiming at the perturbed unified chaotic system, an active adaptive fuzzy integral sliding mode control is proposed. While maintaining the original nonlinear integral sliding mode control transient performance, an improved nonlinear integral sliding mode control method is designed to ensure that The stability of the system is improved.The proposed control method reduces the influence of the uncontrollable state of the unified chaotic system and the approximation accuracy of the adaptive fuzzy compensation term on the system state error.The stability of the system is analyzed based on the Lyapunov stability theory.The numerical simulation results It shows that the unified chaotic system can be controlled to the target point in the presence of parameter perturbation and external perturbation.The numerical simulation shows the effectiveness of the proposed control method.
