Multiobjective ℋ problems: Linear and nonlinear control

Research output: Contribution to journalArticlepeer-review

Abstract

In this note, we compare the value of nonlinear and linear control for a multiobjective ℋ control problem with a linear time-invariant (LTI) plant. We show that if the ℋ performance of a nonlinear feedback controller is measured by the maximum incremental gain, the optimal achievable performance with nonlinear, time-varying control is identical to that achievable by LTI control.
