Abstract
A multiobjective strategy to optimize aircraft e ight dynamics is presented. Instead of using a classical approach where systematic methodologies are scarce to dee ne a suitable cone guration, a two-step procedure is proposed to guide the designer through an eigenstructure-assignment-based control law. First, an ideal model is found by means of a multiobjective optimization strategy that includes constraints both on eigenvalues and eigenvectors. Theproblem issolvedthrough ahybrid procedurethatcombinesgeneticalgorithmswithdeterministiclocalsearch methods. Second, the ideal model is approximated with a variable structure control system to improve the control system robustness. A comparison is shown with examples taken from the literature, where the effectiveness of the proposed methodology is demonstrated.
