Design of fuzzy controller with linear extended state observer for magnetic suspension bearings
2014 17th International Conference on Electrical Machines and Systems (ICEMS), 2014A high performance controller for magnetic suspension bearings is investigated. To improve the robustness of the controller and the suspension accuracy of the system, a fuzzy controller is designed using variable bandwidth triangle membership function. Considering the poor static-state performance of traditional fuzzy controllers, an additional linear ...

A linear extended state observer (LESO) based fuzzy fault tolerant control (FTC) scheme is designed for an over-actuated autonomous underwater vehicle (AUV) to address the faults of actuators. In this scheme, both the faults of the actuators and other immeasurable disturbances are lumped into a generalized total disturbance, which is then estimated by ...

A Gain Design Method for a Linear Extended State Observers to Improve Robustness of Deadbeat Control
IEEE Transactions on Energy Conversion, 2020This article proposes an extended state observer to broaden the stability range of conventional deadbeat controller. The proposed observer is constructed through the model of permanent magnet synchronous machine (PMSM) which considers the parameters mismatch and unmodeled nonlinear elements.

In this paper, two approaches for model following control in the presence of uncertainties are compared. Specifically, the so-called command governor framework, originally developed as an augmentation to adaptive control, and a modified linear extended state observer are evaluated.

AbstractIn this paper, a trajectory linearization control based control law using a linear extended state observer (LESO) is proposed for the output tracking problem of a nonlinear system with uncertainties. First, based on the tracking error dynamics derived by Taylor expansion for the original nonlinear system along the desired trajectory, a feedback
