Generalized dynamic observers for quasi-LPV systems with unmeasurable scheduling functions: Generalized dynamic observers for quasi-LPV systems with unmeasurable scheduling functions

This paper presents a generalized dynamic observer design for polytopic quasi-linear parameter-varying systems where the parameters are depending on unmeasured state variables. It generalizes the existing results on the proportional observers and proportional-integral observers. Conditions of existence and stability are given through the Lyapunov approach. Its design is obtained in terms of a set of linear matrix inequalities. A semiactive suspension example illustrates the performance and effectiveness of the proposed approach.
