Methods for Obtaining Robust Tracking Control Laws

This paper treats the problem of determining a tracking control law for linear system with uncertain parameters. The tracking control is robust in the sense that it achieves asymptotic tracking of the command reference input for all admissible parameter values. Based on the available theoretical results for determining tracking controllers, numerical methods for obtaining the feedback gains for a robust control law are presented. The efficacy of these methods is demonstrated by applying them to two aircraft examples.
