研究了受执行器故障和多重扰动影响的时不变系统的容错控制问题。多重扰动由两种组成：一种是范数有界向量；外源系统描述的另一个被视为具有已知幅度和未知频率和相位的谐波信号。设计了一种改进的扰动观测器，以获得具有部分已知信息的建模扰动。在此基础上，提出了两种新颖的容错控制算法来分析和补偿两种不同类型的执行器故障（一种是范数有界的，另一种是未知边界的）。控制方案的有效性和鲁棒性可以通过不同情况的数值模拟来展示。
The problem of fault-tolerant control for the time-invariant system subject to actuator faults and multiple disturbances is focused. The multiple disturbances are composed of two kinds: one is a norm-bounded vector; the other described by an exogenous system is viewed as a harmonic signal with known amplitude and unknown frequency and phase. An improved disturbance observer is designed to obtain the modelled disturbance with partially known information. Based on this, two novel fault-tolerant control algorithms are put forward to the analysis and compensate two different types of actuator faults (one is norm-bounded, and the other is with an unknown boundary). The effectiveness and robustness of control schemes can be exhibited through some numerical simulations with different cases.
