Underactuated Spacecraft Control with Disturbance Compensation

Abstract

This research focuses on the development and application of three methods for the underactuated spacecraft attitude problem. The first method utilizes Solar Radiation Pressure (SRP) to restore linear controllability to a spacecraft with only two functional Reaction Wheels (RWs). The second method is concerned with the creation of drift sets that characterize initial conditions for a spacecraft with two RWs such that it can perform desired imaging missions given constraints and disturbances torques. The third method describes the use of a hybrid switching scheme for two external moments control and two internal moments control, as well as a Model Predictive Control (MPC) approach for two internal moments control. The advantage to these approaches are that they can be used for zero and nonzero angular momentum. Simulations are done on spacecraft nonlinear models to demonstrate each of the approaches.
