                         FIGURE 4.5 Neural network model design for mini-UAV X-04, flight regime with airspeed V = 70 km/h. (A) Training
                         sample for the ANN model. (B) Efficiency test for a closed-loop ANN model. Here α is the angle of attack, deg; E α is the
                         tracking error (difference between angle of attack values for the object and the ANN model), deg; δ e, act is command signal
                         for the actuator of the elevons; t is time, sec; the solid line is the output of the object; the dotted line is the output of the ANN
                         model.
