This paper presents a comparison between differentcontrol strategies used for estimation purposes for systems withunknown inputs in the recently proposed Control-based Observerapproach. In particular, several robust state and unknown inputsobservers are derived using classical controllers such as Proportionalor Proportional Integral, Linear Quadratic Regulator orLinear Quadratic Integrator and H∞ Full information. They arealso compared with criteria such as the quality of the estimation,the speed of the observers, the robustness against the noise andthe complexity of the observers. Simulation results are providedto better highlight the comparison.
