Modeling and simulation of a Sail
- View All
The objective of this work is to model and simulate the behavior of a new type of satellite system called the Power Sail. The Power Sail concept includes a large solar array, measuring 400m2, that is flown separately from the host satellite but connected via rigid links. The concept calls for two rigid links, which also act as power conduits, connected by a joint. The joint is modeled as being locked with some desired angle between the links. The attitude of the Power Sail system is controlled via thrusters located on the Power Sail solar panel. The natural motion of this system is found to be unstable in the desired nominal configuration. A control law is developed to maintain a desired reference attitude. To minimize reaction forces on the host satellite, a constant reference attitude with the center of mass located on the host orbit is found to be desirable. © 2002 by the author(s).
