Robust asymptotic tracking for linear systems with unknown parameters (Q1072988)

This paper considers a tracking problem for a linear system with uncertain parameters. The objective is to design a state feedback controller so that for all allowable parameter values the system is internally stable and its output asymptotically tracks the command reference input. A controller having this property is termed a robust tracking controller. Conditions are given which can be used to design a robust tracking controller. The controller is linear with readily computable gains. The results are illustrated with an example.
