| Popis: | An adaptive control technique for the unloading of spacecraft angular momentum is presented. The technique employs model reference adaptive control theory with Lyapunov stability analysis to synthesize a controller using multiple environmental sources in combination for unloading. Simulation studies are presented that employ magnetic, gravity gradient, and aerodynamic torques in a three-way controller. It is shown that momentum is contained within a dead zone introduced for disturbance compensation that is well below reasonable reaction wheel saturation limits for two model spacecraft of much different mass properties. |
