Direct yaw-moment control of an in-wheel-motored electric vehicle based on body slip angle fuzzy observer [PDF]
, 2009 A stabilizing observer-based control algorithm for an in-wheel-motored vehicle is proposed, which generates direct yaw moment to compensate for the state deviations. The control scheme is based on a fuzzy rule-based body slip angle (beta) observer.

Delay compensation for nonlinear teleoperators using predictor observers [PDF]
, 2010 This paper presents a delay compensation technique for nonlinear teleoperators by developing a predictor type sliding mode observer (SMO) that estimates future states of the slave operator. Predicted states are then used in control formulation.

A Deadbeat Observer for Two and Three-dimensional LTI Systems by a Time/Output-Dependent State Mapping [PDF]
, 2017 The problem of deadbeat state reconstruction for non-autonomous linear systems has been solved since several decades, but all the architectures formulated since now require either high-gain output injection, which amplifies measurement noises (e.g., in ...

Robust composite temperature control of electrical tube furnaces by using disturbance observer
Case Studies in Thermal Engineering, 2022 As one type of resistance furnace, the electrical tube furnace (ETF) typically experiences input noise, measurement noise, system uncertainties, unmodeled dynamics and external disturbances, which significantly degrade its temperature control performance.

Exact fuzzy observer for a baker’s yeast fed-batch fermentation process [PDF]
, 2007 The purpose of this work is to design an exact fuzzy observer for a bioprocess switching between two different metabolic states. A fed-batch baker's yeast culture is modeled by two sub-models: a respiro-fermentative state with ethanol production and ...
