Abstract

A design methodology is presented which makes it possible to trade off performance with robustness, as characterized by frequency-domain properties, such as loop gain. The basic performance and stability goals are achieved with a nominal linear quadratic regulator design. Frequency-domain issues are then integrated into the design by using, in the next phase of design, a frequency-weighted performance criterion. The structure of this performance criterion allows the eigenstructure associated with the nominal design to be retained. An unstable nonminimum-phase example illustrates the methodology.
