Özet
Controlling the attitude of a satellite with high accuracy and stability under both sensor and actuator delay is a great problem. It is possible to correct for errors, but a robust controller is more preferable. In this study, the attitude of a 3-DoF satellite model incorporating uncertainties (delays in handling both sensors and actuators) is controlled using a suitably designed integral fuzzy variable structure (IFVSC) controller. The attitude control accuracy of the IFVSC is evaluated and compared to other reference controllers (one is a PID controller and the other is a loop shaping controller). IFVSC is found to perform well with Td = 0.2 s sensor and actuator data delay. Copyright © 2020 Inderscience Enterprises Ltd.
