                         FIGURE 4.9 Performance characteristics of the neurocontroller used with a real controlled object and with its ANN model
                         (hypersonic research vehicle X-43, flight regime M = 6). (A) Performance comparison. (B) The reference signal tracking error
                         values. Here E α = α − α rm is tracking error (the difference between the angle of attack values for the controlled object and
                         reference model); the solid line is for the real plant; the dotted line is for the ANN model.
