ABSTRACT
Transition control is defined in this work as a type of control method that is
employed when the plant transitions from one steady state to another as a result
of a set point change. Recent approaches have relied on multiple models and
centralized or decentralized controller designs to address this issue. This work
introduces and develops a transition control framework that consists of multiple
fixed and adaptive models within a state-shared non-minimal realization and an
H-infinity controller design. The efficacy of this transition control
framework is demonstrated on two nonlinear single-input single-output
reactors in the face of modeling errors, parameter uncertainties and
disturbances.
