Fault-tolerant actuator control system for a spaceplane using adaptive control

In this paper, we present a fault-tolerant actuator control system with redundancy for a future spaceplane. The control system based on model reference adaptive control is designed to maintain the control effects with respect to the vehicle rotational motion, even if some of the actuators develop problems or break down. A hardware-in-the-loop simulation involving real DC servo motors was carried out to show the effectiveness of the proposed system.
