Different from a conventional aircraft, an investigation on system identification and control design has been carried out on a small fixed‐wing unmanned aerial vehicle (UAV) with segmented ailerons. The multiple aileron setup is configured as a multi‐input and single‐output system, and each segment is modeled as a control input. Experiments are conducted in the wind tunnel to determine the frequency responses of the system and the corresponding transfer functions. Multiple PID controllers are designed and implemented in a cascaded form for each control surface. Furthermore, a heuristic switching control strategy is implemented for the aircraft where the multiple aileron segments perform as a single aileron pair in a normal flight condition and adapt to multi‐segment control when encountering severe turbulence or significant angle reference changes. Experimental results reveal that although each control surface can stabilize the aircraft, the proposed control strategy by combining the multiple actuation surfaces reduces the mean squared errors for the roll angle up to 38 percent in the highly turbulent en vironment providing superior disturbance rejection properties.
