A control system for the Marine Corps Airborne Remotely Operated Device is described. This unmanned air vehicle is designed to provide frontline Marines with a portable, short range, aerial reconaissance capability. The chosen configuration has a single gasoline engine and propeller enclosed in an airfoil shroud with four aerodynamic control surfaces located just aft of the shroud. The control system is designed to provide stability augmentation so that a Marine with minimal training will be able to fly the vehicle. One interesting aspect of the control problem is the gyroscopic coupling between two of the control channels due to the single propellor design. The multi-input/ multi-output nature of this problem has been the motivation for the use of a linear-quadratic-regulator controller synthesis technique. Simulation time responses and a singular value analysis are employed to assess the performance of the control system. A limited flight test program has also been used to evaluate performance.
