Abstract This paper gives a brief survey of linear and nonlinear Proportional-Integral- Observer design. This observer has the ability to estimate simultaneously the states and unknown inputs such as disturbances or model uncertainties acting on the system. In literature different system types have been considered for designing PI-Observer which are introduced briefly in this survey. Furthermore design methods of Advanced PI-observer and Modified Advanced PI-Observer are presented. Both approaches are based on the PI-Observer but using adaptive gain scheduling approach. Simulation results using American Control Conference (ACC) benchmark are given to evaluate Modified Advanced PI-Observer in comparison to PI- Observer and Advanced PI-Observer.
