Robust state-derivative pole placement LMI-based designs for linear systems
(Taylor & Francis Ltd, 2009-01-01)
In some practical problems, for instance in the control systems for the suppression of vibration in mechanical systems, the state-derivative signals are easier to obtain than the state signals. Necessary and sufficient ...
Robust controller design of a wheelchair mobile via LMI approach to ERP systems with feedback output
(2015-05-01)
This article discusses the design of robust controller applied to Wheelchair Furniture via Linear Matrix Inequalities (LMI), to obtain Strictly Positive Real (SPR) systems. The contributions of this work were the choice ...

H 2/H ∞ formulation of LQR controls based on LMI for continuous-time uncertain systems
(2021-01-01)
The classical theory of linear matrix inequality (LMI)-based linear quadratic regulator (LQR) control that is well established in literature does not provide, in the controller project phase, the occurrence of exogenous ...
Design of a state observer using decay rate LMI constraints for fault detection in mechanical systems
(2010-01-01)
Nowadays, one of the most important concerns for many companies is to maintain the operation of their systems without sudden equipment break down. Because of this, new techniques for fault detection and location in mechanical ...

LMI-based algorithm for strictly positive real systems with static output feedback
(Elsevier B.V., 2012-04-01)
An algorithm based on Linear Matrix Inequalities (LMIs) is proposed to find a constant output feedback matrix K-0 and a constant output tandem matrix F such that the controlled system {A - BK0C, B, FC} is Strictly Positive ...
Alocação de zeros aplicada a sistemas de controle via LMI
(2007-02-01)
A systematic procedure of zero placement to design control systems is proposed. A state feedback controller with vector gain K is used to perform the pole placement. An estimator with vector gain L is also designed for ...
