Simulations of spacecraft attitude control for tracking maneuvers with MATLAB and STK

The spacecraft attitude tracking control problem and its MATLAB-STK simulation is researched in this paper. First, an attitude dynamic modal for tracking maneuvers based on error quaternion is established. And based on this dynamic modal a sliding mode variable structure controller is designed. Then, a simulation and visualization based on MATLAB-STK is finished. By ordering MATLAB to call for STK/Connect module, data can be communicate in both software. And it makes visualization of simulation result very easily in STK. The Simulation illustrate the performance of the proposed controllers.
