Abstract
One of the distinguishing features of the flying wing layout aircraft is that it has more pneumatic control surfaces. The control surfaces are commonly designed at the tail, distributed on both sides of the UAV design axis and away from the center of gravity of the drone. When a single control surface is deflected, Torque is generated on the three-axis channel, which brings about the problem of control coupling. In order to solve this series of problems, this control allocation technology begins to receive more and more attention. The issue of control allocation of multiple control surfaces is essentially an optimization problem. This paper mainly focuses on a flying wing layout drone, explores the target optimization problem of the multiple control surfaces’ control allocation, and designs an algorithm to achieve the optimization target according to different mission objectives, and gives the simulation with minimum resistance and minimum radar reflection area as targets. Simulation results illustrate that this method can achieve the expected target under the premise of ensuring the steering torque.
