RESULTS OF COMPUTATIONAL EXPERIMENTS WITH ADAPTIVE SYSTEMS 243

FIGURE A.17 The results of a computational experiment for the MRAC-type control system with compensator (hyper-
sonic research vehicle X-43, flight mode M = 6). Adaptation to the change in the dynamics of the controlled object: backwards
shift of the center by 5% (t = 20 sec); 50% decrease in the effectiveness of the control (t = 50 sec). 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 reference
signal on the angle of attack, deg; δ e, act is command signal for the elevator actuator, deg; t is time, sec.
