To provide a safe and efficient test for the autonomous control design of the unmanned helicopter, a 3 degree-of-freedom (DOF) helicopter testbed is developed in this paper. The testbed uses a small electric hobby helicopter as the main body, a digital signal processsor (DSP) is employed as the on-board micro control unit (MCU) for the attitude control of the helicopter, a micro attitude and heading reference system (AHRS) is utilized as the main on-board sensor for attitude states feedback and a Bluetooth module is mounted on the testbed to provide realtime wireless communication between the helicopter and the ground control station (GCS). This paper investigates the servo actuators coordinated control method with separate channel of the new-style electric helicopter, which is named as electronic collective-cyclic pitch mixing (ECCPM). A modified digital incremental PID control algorithm which is free of servo actuators saturation issue is proposed for the attitude control of the helicopter. Finally, experiment results are provided to verify the testbed and control design.

A ground control system (GCS) for unmanned aerial vehicles (UAV) is developed in this paper. Different tasks, which include real time communication between GCS and UAVs, data processing and storing, localization, path planning and so on, can be accomplished in the proposed GCS. To address the issue of path planning problem for UAVs, a new path planning algorithm based on potential function is proposed to drive the UAV to its destination in this paper. Time-varying gain adjusting method is used to enable the UAV obstacle avoidance ability under the constraints for the translation velocity. Lyapunov based analysis is used to prove the stability of the proposed algorithm. Numerical simulation results are included to demonstrate the performance of the proposed path planning design.

In this paper, a distributed approach to Model Predictive Control (MPC)-based trajectory planning for rotary-wing UAV (Unmanned Aerial Vehicle) communication network topologies under radio path loss constraints is proposed. The goal is to find trajectories that are safe with respect to grounding and collision, fuel efficient and satisfy criteria for communication such that the UAVs form chains to multiple targets with given radio communication capacities. The MPC-based optimization sub-problems are computed autonomously within each UAV, using convex quadratic programming, with the requirement that each UAV communicates its current measured position to all other UAVs. In addition, a simple coordination between UAVs allows for the communication network topology to be reconfigured in case of failures or radio path loss changes. The control performance of the distributed linear MPC trajectory planning is studied based on a simulation case with four UAVs and two targets.

The four-rotor unmanned aerial vehicle (UAV), known as quadrotor UAV, has been a hot area for the research of unmanned aerial vehicles. Ground Control Station (GCS), as an essential part of quadrotor UAV system, plays a very important role in applications of quadrotor UAV. Most ordinary GCS are stand alone ones, and lack extending abilities. Considering this defect and the real requirements of monitoring and control of UAV, this paper provides a new GCS based on VC++ and Java programming techniques. The major novelty of this GCS is of the Web access to real-time flight data. Plus, the proposed GCS posses the standard functions, such as data receiving in real time, storing the data and displaying the data. Experiment results are provided to show that the GCS operates well, with good human-machine interaction and extending abilities. © 2012 Chinese Assoc of Automati.

In recent years, quadrotor helicopter has become a hotspot of the research about unmanned aerial vehicles (UAVs). The data acquisition of the vehicle's attitude and position in real time is important to achieve autonomous flight control for quadrotor UAVs. In this paper, an ARM embedded system is employed as the main controller, and an attitude heading reference system (AHRS) is utilized as the main onboard sensor. By using C++ programming under Linux operation system, the data acquisition and processing of the AHRS is implemented, and then the attitude and position data of the quadrotor UAV are obtained in real time to provide reliable flight state information for the autonomous flight control. The on-board flight data is sent to ground control system and stored via a communication module based on the UDP network protocol.

In April 2006, a terrain-relative navigation experiment successfully flew on a sounding rocket mission at White Sands Missile Range. The mission was designated by NASA/Wallops Flight Facility as 41.068 NT/Seybold ("41.068") and was flown as part of the New Millennium Program ST9 Terrain-Relative Guidance system (TRGS) Project's competitive Phase A effort. The TRN experiment had two objectives: 1) To demonstrate the viability of a navigation filter for precision landing that uses on-board IMU and descent image data to achieve position knowledge errors of less than 100m, validated with GPS data recorded during flight;and 2) To establish that commercial off-the-shelf cameras can be packaged sufficiently well to survive the sounding rocket launch environment. Both objectives were met. The 13 min flight provided a data set that was processed post-flight through the prototype algorithms to bring the ST9 TRGS Project to a technology readiness level of 4 in TRN. This paper describes the flight system development and operations of the TRN experiment on 41.068.
