We proposed the design of a controller to regulate the voltage on the DC Bus for a hybrid UAV, which integrates a primary power source (a fuel cell or an internal combustion engine) with a battery, which extends the flight time. The controller must supply a regulated voltage to the UAV using two DC/DC converters. The first converter is between the DC bus and the battery, accumulates energy, and holds the voltage. Found the second converter between the primary power supply and the DC Bus, controlling the input voltage.The executed simulations demonstrate the effectiveness of integrating this control system in the hybrid UAV to regulate the voltage required for various manoeuvres.

The wide spectrum of recent applications for UAVs imposes further challenges to their abilities and control. This is especially true when operating in harsh and hostile environments where disturbances are huge and actuators are prone to failure. Conventional systems and traditional control techniques are not sufficient for stability and tracking under these circumstances. This paper proposes a unique innovative overactuated quadrotor system that has six DoFs. The vehicle has four rotors and each rotor can tilt independently in the [Formula: see text]-plane. It has the ability to correct its position and attitude in a decoupled way which is different from the conventional quadrotor configurations. Sliding-mode control associated with switching control mode is used for the control algorithm of the system. The system shows agility in the face of large disturbances and robustness against actuator failure which makes it a perfect fit for extreme and challenging environments. The concept of the system and its ability are illustrated in simulation with promising results.

“…Wang et al combined a multirotor aircraft with a fixed wing, determined the design plan after wing selection and plan layout, and used fluid-structure interaction to prove that the fixed-support boundary is the point of maximum stress (Wang et al , 2019). Zeng et al designed an aircraft with a combination of rotor and duct, obtained the corresponding layout plan through aerodynamic performance analysis and optimized the duct, and finally designed a prototype to verify the feasibility of the design (Zeng et al , 2020). Zhu et al proposed a two-ring strategy to solve the design problem of folding wing aircraft.…”

Purpose To solve the problems of short battery life and low transportation safety of logistics drones, this paper aims to propose a design of logistics unmanned aerial vehicles (UAV) wing with a composite ducted rotor, which combines fixed wing and rotary-wing. Design/methodology/approach This UAV adopts tiltable ducted rotor combined with fixed wing, which has the characteristics of fast flight speed, large carrying capacity and long endurance. At the same time, it has the hovering and vertical take-off and landing capabilities of the rotary-wing UAV. In addition, aerodynamic simulation analysis of the composite model with a fixed wing and a ducted rotor was carried out, and the aerodynamic influence of the composite model on the UAV was analyzed under different speeds, fixed wing angles of attack and ducted rotor speeds. Findings The results were as follows: when the speed of the ducted rotor is 2,500 rpm, CL and K both reach maximum values. But when the speed exceeds 3,000 rpm, the lift will decrease; when the angle of attack of the fixed wing is 10° and the rotational speed of the ducted rotor is about 3,000 rpm, the aerodynamic characteristics of the wing are better. Originality/value The novelty of this work comes from a composite wing design of a fixed wing combined with a tiltable ducted rotor applied to the logistics UAVs, and the aerodynamic characteristics of the design wing are analyzed.
