Research Topics


Accurate Automation Corporation (AAC) will apply the latest knowledge in optimal control, adaptive control, and learning control to develop a state-of-the-art, adaptive, nonlinear, package for robust satellite guidance and control. The guidance module will generate an optimal trajectory between pre-defined way-points and the control module will ensure robust and accurate trajectory tracking. The controller will be cased on an improved version of an n (sup th) order multivariate Neutral Adaptive Controller (NAC (sup TM)) developed at AAC. And the guidance system will use a neutral network based adaptive critic.
