Based on the linearized model both controllers are designed to be comparable, i. e. they show a similar crossover frequency in the open loop and the final controller order is reduced to the same range for both designs.

The key idea of this contribution is the partial compensation of non-minimum phase zeros or unstable poles.

In this paper, we propose the concept of accelerated convergence that has originally been developed to speed up the convergence of numerical methods for extremum seeking (ES) loops.
