RESULTS OF COMPUTATIONAL EXPERIMENTS WITH ADAPTIVE SYSTEMS      287




















































                          FIGURE A.61 The results of a computational experiment on adaptation to uncertainty in the source data for an MRAC
                          control system applied to the hypersonic research vehicle X-43 (flight mode M = 5, H = 28 km, ω rm = 2). 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.
