摘　　要：针对一类执行器及传感器同时发生故障的非线性系统,综合鲁棒滑模重构观测器及自适应滑模容错控制器设计技术,提出一体化跟踪主动容错控制方案.首先,将系统增维变换为广义系统,运用广义约束逆引入辅助矩阵,采用线性矩阵不等式设计观测器系数矩阵,综合自适应律给出广义鲁棒滑模观测器设计程式;在此基础之上,通过设计鲁棒滑模微分器估计输出向量微分,结合广义鲁棒滑模观测器状态估计结论,实现执行器及传感器故障同时重构.其次,基于故障重构及状态估计结论,提出自适应滑模的跟踪主动容错控制律设计程式.最后,通过开展飞行模拟转台伺服系统数值仿真,检验一体化跟踪主动容错控制器设计方法的有效性.An active fault tolerance control algorithm is proposed for the nonlinear system with actuator and sensor faults simultaneously,which is combined with the robust sliding mode observer and adaptive sliding mode controller design.Firstly,the extended state vector is introduced,and the original system is transformed into the descriptor system.Then for the descriptor system,a descriptor robust sliding mode reconstructed observer with adaptive law is proposed,where the auxiliary matrix is introduced through generalized inverse under constraints,and the coefficient matrices are given through linear matrix inequality,meanwhile,a robust sliding mode differentiator is proposed for estimating the output vector differentiator,thus the actuator and sensor fault reconstructed results are obtained simultaneously.Thirdly,the adaptive sliding tracking fault tolerance controller is proposed based on the fault and state reconstruction results.Finally,an example of the flight simulator servo system is provided to validate the effectiveness of the fault tolerance control algorithm.
