Abstract:

This project is performed under the Office of Naval Research program on Basic and Applied Research in Sea- Based Aviation ONR BAA12-SN-0028. This project addresses the Sea Based Aviation SBA initiative in Advanced Handling Qualities for Rotorcraft. This project seeks to develop advanced control law frameworks and design methodologies to provide autonomous landing or, alternatively, a high level of control augmentation for pilot-in-the-loop landings. The design framework will focus on some of the most critical components of autonomous landing control laws with the objective of improving safety and expanding the operational capability of manned and unmanned rotorcraft. The key components include approach path planning that allows for a maneuvering ship, high performance station-keeping and gust rejection over a landing deck in high windssea states, and deck motion feedback algorithms to allow for improved tracking of the desired landing position and timing of final descent. Work at Penn State has been directed towards transitioning the Dynamic Inversion DI Control Laws CLAWS to the Flightlab Control System Graphical Editor CSGE. PSU has developed scripts in Flightlab to automate generation of linear models and synthesis of inverse model tables.
