Abstract
It is shown that tunable digital controllers incorporating dynamic pole-assignment compensators for open-loop unstable multivariable plants with time-invariant parameters can be readily rendered adaptive so as to cope with such plants with time-invariant parameters. The effectiveness of such an adaptive digital controller incorporating a dynamic pole-assignment compensator is illustrated by designing an adaptive set-point tracking controller for the STOL (short takeoff and landing)/F-15 aircraft in a light condition for which this aircraft is open-loop unstable. It is demonstrated that the adaptive controller rapidly 'learns' the dynamical characteristics of the STOL/F-15 aircraft so that noninteracting set-point tracking is soon achieved with practically acceptable control-surface deflections.Keywords
