An Adaptive Nonlinear Controller for DFIM-Based Wind Energy Conversion Systems
(Institute of Electrical and Electronics Engineers, 2008-12)
An adaptive nonlinear controller for wind energy doubly fed induction machines is introduced in this paper. The proposed controller is based on the feedback linearization technique and includes a disturbance observer for ...
Numerical stability analysis and control of umbilical-ROV systems in one-degree-of-freedom taut-slack condition
(Springer, 2007-07)
In this paper, the stability of an umbilical-ROV system under nonlinear oscillations in heave motion is analyzed using numerical methods for the uncontrolled and controlled cases comparatively. Mainly the appearance of the ...
A cost reduction procedure for control-restricted nonlinear systems
(Praise Worthy Prize, 2017-11)
This paper describes a numerical scheme to approximate the solution of the optimal control problem for nonlinear systems with restrictions on the manipulated variables. The method proposed here systematically reduces the ...
Optimum viscoelastic absorbers for cubic nonlinear systems
(Sage Publications Ltd, 2014-07)
Dynamic vibration absorbers are efficient devices used in vibration and noise control of several mechanical systems. In recent years, some studies about these control devices comprising systems with nonlinear characteristics ...
