On an Optimal Linear Control of a Chaotic Non-Ideal Duffing System
(Trans Tech Publications Ltd, 2012-01-01)
In this work, we use a nonlinear control based on Optimal Linear Control. We used as mathematical model a Duffing equation to model a supporting structure for an unbalanced rotating machine with limited power (non-ideal ...
Effects of the thyristor controlled serie capacitor on the electric power system
(2004-12-01)
This work deals with the effects of the series compensation on the electric power system for small-signal stability studies. Therefore, the system is modeled admitting the existence of the compensation and then, the equations ...
Vibration Control Applied in a Semi-Active Suspension using Magneto Rheological Damper and Optimal Linear Control Design
(Trans Tech Publications Ltd, 2014-01-01)
In this paper we study the behavior of a semi-active suspension witch external vibrations. The mathematical model is proposed coupled to a magneto rheological (MR) damper. The goal of this work is stabilize of the external ...
Linear quadratic Gaussian control of discrete-time Markov jump linear systems with horizon defined by stopping times
(2005-12-01)
The linear quadratic Gaussian control of discrete-time Markov jump linear systems is addressed in this paper, first for state feedback, and also for dynamic output feedback using state estimation. in the model studied, the ...
Multi-area decentralized optimal VAr planning using the Dantzig-Wolfe decomposition principle
(2011-05-31)
This paper presents a new methodology for solving the optimal VAr planning problem in multi-area electric power systems, using the Dantzig-Wolfe decomposition. The original multi-area problem is decomposed into subproblems ...
LMI-based digital redesign of linear time-invariant systems with state-derivative feedback
(2009-12-01)
A simple method for designing a digital state-derivative feedback gain and a feedforward gain such that the control law is equivalent to a known and adequate state feedback and feedforward control law of a digital redesigned ...
Control Design Applied to a Micro Electro Mechanical System: MEMS Comb drive
(Trans Tech Publications Ltd, 2011-01-01)
This paper presents the linear optimal control technique for reducing the chaotic movement of the micro-electro-mechanical Comb Drive system to a small periodic orbit. We analyze the non-linear dynamics in a micro-electr ...
