L-2 State Estimation With Guaranteed Convergence Speed in the Presence of Sporadic Measurements [PDF]

, 2019
This paper deals with the problem of estimating the state of a nonlinear time-invariant system in the presence of sporadically available measurements and external perturbations. An observer with a continuous intersample injection term is proposed.

Experimental State Observer of the Population Inversion of a Multistable Erbium-Doped Fiber Laser

Photonics
In this work, numerical and experimental implementation of a state observer applied to an erbium-doped fiber laser (EDFL) has been developed. The state observer is designed through the mathematical model of the EDFL to estimate the non-measurable ...

High-Precision Position Tracking Control with a Hysteresis Observer Based on the Bouc–Wen Model for Smart Material-Actuated Systems

Actuators
The Bouc–Wen model has been widely adopted to describe hysteresis nonlinearity in many smart material-actuated systems, such as piezoelectric actuators, shape memory alloy actuators, and magnetorheological dampers.

Sensorless Control of CSI-Fed PMSM Drives Based on Improved Extended State Observer

Energies
To address the problem that the maximum error of back-EMF observers increases with an increase in motor speed, based on an extended state observer, this paper designs an angle-compensation strategy based on a proportional–integral controller and an ...
