This paper presents an active fault-tolerant control( FTC) architecture for satellite attitude control system(ACS) by combining iterative learning ideology and unknown input observer(UIO). As an integral part of active FTC system(FTCS), a learning UIO(LUIO) is proposed to achieve attitude angular velocities estimation and robust reconstruction of adaptive compensation law simultaneously based on the...
This paper is concerned with the design problem of robust fault-tolerant controller of linear uncertain satellite attitude control systems. The design method of output feedback robust fault-tolerant controller with failures of actuators and sensors is proposed to meet the given control performance by using LMI method. A numerical example of satellite attitude fault-tolerant control system is given...
This paper did research on fault-tolerant control of satellite control system. Based on general discussion over all available fault-tolerant control methods, we chose linear matrix inequation (LMI) to do research on robust fault-tolerant control. The result could apply to the control problem of three-axis stabilized directional satellite control system. Also, we use our result on fault diagnosis of...
