Design of unknown input fuzzy observer for vehicle dynamics estimation with road geometry consideration

A methodology for estimating vehicle dynamics whith road geometry consideration is presented in this paper. Vehicle sideslip and roll parameters are estimated in the presence of the road bank angle and the road curvature as unknown inputs. The unknown inputs are then estimated using the observer results. This information about the road geometry and vehicle parameters is needed in the driver ass...

On non-linear unknown input observers-applied to lateral vehicle velocity estimation on banked roads

Unknown input observers (UIOs) are observers that have stable error dynamics that are independent of unknown inputs. This paper studies such observers for nonlinear systems, and shows that the error dynamics for a nonlinear UIO has the same structure as the error dynamics of a nonlinear observer without unknown inputs. This result is first used to provide synthesis inequalities for UIOs for a c...

Interval observer for LPV systems: Application to vehicle lateral dynamics

This paper presents a new method for guaranteed and robust estimation of sideslip angle and lateral tire forces with consideration of cornering stiffness variations resulting from changes in tire/road and driving conditions. An interval LPV observer with both measurable and unmeasurable time-varying parameters is proposed. The longitudinal velocity is treated as the online measured time-varying...

Unknown Input Full Order Observer Construction Using Generalized Matrix Inverse

In this paper a design methodology is proposed to provide a constructive solution to the problem of designing a full order observer for linear time invariant systems subjected to unknown disturbances. Necessary conditions for existence of unknown input observers are stated and solved using generalized matrix inverse. The effect of unknown disturbance present in the system is eliminated from the...
