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
