Abstract
The issue of reconfiguration-based fault-tolerant control for systems with actuator fault and saturation is addressed. The basic idea behind this work is to evaluate the system reconfigurability to guide the reconfiguration scheme and system structure design. First, a reconfigurability criterion is derived and utilized to quantify the degree of reconfigurability. On this basis, a passive/active combined reconfiguration method is proposed to balance the effectiveness and implementation complexity of the reconfiguration scheme. Moreover, the system structure is optimized to further improve the comprehensive performance of the system. Finally, the effectiveness of the proposed method is illustrated through an application example of the satellite attitude control system.
