Abstract

It is shown that tunable digital controllers can be readily enhanced so as to cope with one-loop unstable multivariable plants, which can be either nonminimum-phase or minimum-phase by incorporating dynamic pole-assignment compensators. Such inner-loop compensators facilitate the use of outer-loop PID controllers. The effectiveness of such a tunable digital controller is illustrated by designing a set-point tracking controller for the STOL/F-15 aircraft in a flight condition for which this aircraft is open-loop unstable
