The interface is also used to connect to the Multi-Platform Vehicle Test Set (MPVTS). This interface is used to load initialization parameters and flight information into the IFC. ![]() It also communicates to the Ground Support Equipment (GSE) via an EIA RS-422 serial umbilical interface. It gathers heading, pitch angle, roll angle, pitch rate, roll rate, and yaw rate. The IFC Message Processor also communicates with the attitude sensor package (ASP) via EIA RS-485 at a 100 Hz rate. The IFC also transmits downlink telemetry information (UAV performance information) to the ground control station. It receives uplink commands from the ground control station and outputs control signals to the UAV. The IFC communicates with a Command Data Link Transponder via EIA RS-485 serial interfaces. We first give a brief review on the historical development of the rotorcraft unmanned aerial vehicles (UAVs), and then move on to present a fairly detailed and general overview on the hardware configuration, software integration, aerodynamic modeling and automatic flight control system involved in constructing the unmanned system. This includes recovery to stable flight conditions, while performing commanded maneuvers, and control for escape maneuvers of individual drones under all flight conditions. The IFC provides autonomous control functions to assure safe operation of the aircraft in the event of command datalink loss. These two functions are performed by a single high performance PowerPC processor. The IFC Message Processor contains the datalink encode/decode and autopilot functions. ![]() ![]() The IFC supports multiple high performance maneuvers, such as barrel rolls, high G turns, and low altitude operation. The IFC accepts commands from a ground control system (such as GRDCS, SNTC, or TTCS), inputs current vehicle operating parameters from onboard sensors, and outputs control signals to the vehicle for flight control. Our fly-by-wire controls the first in commercial aircraft continue to make flight more agile, secure, and affordable. In this paper, we present the design and development of a. The Integrated Flight Controller (IFC) controls the entire flight functionality and maneuverability of the BQM-167 subsonic aerial target platform. Small unmanned aerial vehicles (UAVs) are becoming popular among researchers and vital platforms for several autonomous mission systems.
