“…The UAV is divided in to two categories, one is fixed wing and second is rotor craft UAV's. However, rotor craft UAV's have an advantage it does not need a runway to execute a flight because of its Vertical Takeoff and Landing (VTOL) ability [2][3][4]. Furthermore, the rotor craft UAV's are also classified in to bi-rotor, tri-rotor, quad-rotor and hex-rotor crafts, having Multiple Input and Multiple Output (MIMO) underactuated systems.…”

“…The key contributions of this article are: (1) an adaptive sliding surface is proposed to remove the steady state error and for the rejections of model uncertainties (2) the designed ASMC uses linear and angular velocity subcomponents as an input providing practical inside of the real world scenario (3) in spite of the model uncertainties, close loop errors in the UAV system converges to zero, which is proved in the simulation and result section (4) stability of the system is proven by Lyapunov stability function.…”

Abstract. Previous studies have shown that Terra moderate resolution imaging spectroradiometer (MODIS) has low detection and characterization efficiency when mapping a green tide (Ulva prolifera) in the Yellow Sea. To quantify the uncertainty in mapping of the green tide using MODIS data, comparisons were conducted between quasi synchronous MODIS images and in situ observation data, as well as an unmanned aerial vehicle (UAV) image. The results show that MODIS images could detect the location of large (>100 m) floating green algae patches with good positional accuracy but tended to ignore the existence of small patches less than 10 m in width. The floating macroalgae area extracted using MODIS was several times larger than the area mapped using the UAV image. The Sentinel-2 multispectral instrument, the Chinese highresolution GF-1 wide field camera, and the Chinese HJ-1 charge-coupled device are recommended for early green tide detection, whereas MODIS is suitable for green tide monitoring. The UAV could also play an important role in regional green tide monitoring with the advantages of flexibility, smaller dimensions, high spatial resolution, and low cost.

“…As the speed of the aircraft increases, the proportion of the total lift of the wing is gradually increased, and the lift proportion of the rotor is gradually reduced until the helicopter mode is completed. Fixed-wing mode of conversion, the wing provides the required lift aircraft, the rotor to provide a pull to overcome the resistance of the aircraft flight process [4][5]. In this paper, the general theory of the modeling of the Tilt tri-rotor UAV is given by modeling the power system of the tilt tri-rotor UAV with the positive triangular layout, and the research of the unmanned aerial vehicle The theoretical basis.…”

Abstract. According to the basic principles of fixed-wing aircraft and multi-rotor design, combined with power requirement of the tilt tri-rotor UAV three flight modes, gives the tilt tri-rotor UAV power system model to solve the tilt tri-rotor UAV electric UAV power system matching problem, and to apply the theory completed a tilt tri-rotor UAV production, flight test was carried out to verify the theory. The experimental results analysis, tilt-rotor aircraft power system model in this paper can meet the general tilt rotor UAV power system design requirements. This achievement can provide theoretical references such UAV power system design.
