摘要
针对仿射非线性系统 ,采用自适应模糊系统进行非线性补偿 ,提出了一种基于自适应模糊状态观测器的鲁棒故障检测方法。为确保观测器对噪声干扰和系统参数不确定误差的鲁棒性 ,给出了闭环系统在有界噪声干扰和系统参数不确定误差下的稳定性定理 ,并进行了详尽的证明。
A robust fault detection scheme based on adaptive-fuzzy state observers for affine nonlinear systems is presented,and adaptive-fuzzy systems is adopted to repair nonlinear parts.To guarantee the robustness of observers under the external disturbance and the internal system parameter error,the stability theorem is proposed and proved in detail.The simulation results demonstrate the efficiency and robustness of the method for disturbance and system parameter uncertainty.
