Multi-objective controller design via optimal interpolation with an aircraft control application

In this paper, a controller design methodology is proposed to satisfy a set of closed-loop objectives simultaneously. The set of objectives consists of: 1) pole placement, 2) decoupled command tracking of step inputs at steady-state, and 3) minimization of step response transients with respect to envelope specifications. The proposed multi-objective control is applied to a simplified lateral/directional dynamics of an L-1011 aircraft at cruise flight conditions.
