General Feedback Control for Distributed Flow Control Devices

ORI proposes a preliminary design of a micro air vehicle (MAV) with integrated active flow control actuators and feedback control system to control longitudinal dynamics of the vehicle without conventional flight control surfaces. The proposed hierarchical control system is composed of Intelligent Control Modules (ICMs) for regulation of local flow behavior and a Global Control System (GCS) for coordination of individual ICM actions providing necessary vehicle stability and control. Empirical data gathered during wind tunnel studies of a model MAV will provide the foundation for the proposed control system. Phase I of the program will design a micro actuator control system integrated with an MAV to control performance utilizing a proposed advanced, nonlinear hierarchical control system to direct the behavior of multiple AFC devices. Increased performance with respect to some or all of the following will be estimated: range, payload weight, payload volume, landing speed, loiter time, and maneuverability. In Phase II the MAV will be constructed and demonstrated in flight and in wind tunnel tests over a range of flight conditions. Increased performance attributable to the AFC, relative will be quantified and documented.
