Robust Cascade Controller for Nonlinearly Actuated Biped Robots: Experimental Evaluation
(2004-06-26)
In this paper we consider the postural stability problem for nonlinearly actuated quasi-static biped robots, both with respect to the joint angular positions and also with reference to the gripping effect between the ...
Observer-based adaptive control using multiple-models switching and tuning
(Institution of Engineering and Technology, 2014-02)
Despite the remarkable theoretical accomplishments and successful applications of adaptive control, this field is not mature enough to solve challenging problems where strict performance and robustness guarantees are ...
Multi-machine power system stability improvement using an observer-based nonlinear controller
(Elsevier Science Sa, 2012-01)
Control and operation of electric networks undergo several changes due to growing energy coming from renewable sources and demanding power quality standards. New dynamic load features also pose a challenge to grid designers. ...
Use of piecewise linear models for optimal control of nonlinear systems
(Institute of Advanced Scientific Research, 2009-12)
The optimal feedback control of nonlinear process is attacked in this paper. The solution of this problem is numerically computed using a Continuous Piecewise Linear (CPWL) approximation of the Ordinary Differential Equations ...
Tracking Control Design in Nonlinear Multivariable Systems: Robotic Applications
(Hindawi Publishing Corporation, 2019-08)
In this work, a controller design technique called linear algebra based controller (LABC) is presented. The controller is obtained following a systematic procedure that is summarized in this work. In addition, the influence ...
Comparison among nonlinear excitation control strategies used for damping power system oscillations
(Pergamon-Elsevier Science Ltd, 2012-01)
This work is focused on the problem of power system stability. A thorough description of nonlinear control strategies for synchronous generator excitation, which are designed for damping oscillations and improving transient ...
Simultaneous state estimation and control for nonlinear systems subject to bounded disturbances
(Cornell University, 2019-06)
In this work, we address the problem to solve simultaneously state estimation and control of nonlinear systems under bounded disturbances using a moving horizon approach. Besides, necessary and sufficient conditions to ...
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 ...
