310                 RESULTS OF COMPUTATIONAL EXPERIMENTS WITH ADAPTIVE SYSTEMS






















































                         FIGURE A.84 The results of a computational experiment to evaluate the significance of the adaptation mechanism in the
                         MRAC control system for the hypersonic research vehicle X-43 (flight mode M = 7, H = 28 km, ω rm = 3). Here α is angle of
                         attack, deg (dotted line for reference model, solid line for plant); E α is tracking error for the given angle of attack, deg; α ref
                         is the reference signal on the angle of attack, deg; δ e, act is the command signal for the elevator actuator, deg; t is time, sec.
