This book presents a method and a toolbox of Matlab & Simulink programs that are used to generate the dynamic model of a multi-body system for space applications. Two comprehensive examples of multi-body spacecraft along with their Matlab files are presented in this book. The multi-body system that is treated by this method, is composed of a main body (hub) with rigid and flexible bodies attached to it, such as solar panels, antennas, propellant tanks, ..etc. The appendages can be connected to the hub by cantilever or pivot joints. In addition to that, the appendages can have an infinite...
