摘要 讨论不确定动态系统的执行器故障检测与重构问题.以滑模观测器为基础,利用状态和输出变换方法与奇异值分解方法相结合对系统进行降阶,提出一种鲁棒故障重构观测器.给出了优化滑模策略,并作了严格论证,保证对系统不确定性具有鲁棒性和跟踪系统状态的收敛性.应用等价输出控制的概念和设计的鲁棒故障重构观测器,获取故障信息并实现执行器故障的检测与重构.最后通过数值仿真验证了该方法的有效性和可靠性. The problems of actuator fault detection and reconstruction in the uncertain dynamical systems are considered. Based on the sliding-model observers, the state and output transformation is combined with singular value decomposition to decompose the dynamical system. A robust fault reconstructing observer is presented. An optimizing sliding-model strategy is given, and the strict verification is done to guarantee the robustness for uncertainties of systems and the convergence rate. Actuator fault is detected and reconstructed by applying the designed robust fault reconstructing observer and the equivalence output control concept. Numerical simulation results show the effectiveness and reliability of the proposed approach.
