Abstract
Controlling spacecraft attitude is critical to mission success and usually deep nonlinear, application-specific techniques are employed to achieve it. The intent in this work is to successfully apply the well-known classical and modern approaches to control a spacecraft mockup, obtaining satisfactory stability and performance. The setup consists of a single reaction wheel (RW) working as the actuator of the control system, and attitude determination is provided by a gyroscope. Also, the mockup contains a cubic body with two panels acting as solar array wings, and all aforementioned components are installed on a spin table to mimic spacecraft behavior. Classical control design included: frequency domain curve fitting; compensator design; and hardware implementation. Modern control application comprised: finding a minimal state-space representation of the model; frequency domain curve fitting; full-state feedback control design; full-state observer design; and hardware implementation.
