New Design of Robust LQR-State Derivative Controllers via LMIs
(2018-01-01)
The resolution of linear quadratic regulator's problem (LQR) approached via linear matrix inequalities (LMIs) for linear and time-invariant systems is proposed in this work. The design of the controllers is based on the ...
Less conservative conditions for robust LQR-state-derivative controller design: an LMI approach
(Taylor & Francis Ltd, 2021-03-02)
This study proposes less conservative conditions for robust linear quadratic regulator controllers using state-derivative feedback (SDF). The algebraic Ricatti equation was formulated using the SDF, and its solution was ...
Fractional PID controller with lqr proportional action applied to fractional model of cement rotary kiln
This paper presents the design of a fractional
controller, which is applied to a fractional MISO model for
cement rotary kiln. The designed controller is a combination of a
fractional PID and a Linear Quadratic Regulator ...
Less conservative conditions for the robust and Gain-Scheduled LQR-state derivative controllers design

Neste trabalho é proposta a resolução do problema do regulador linear quadrático (Linear Quadratic Regulator - LQR) via desigualdades matriciais lineares (Linear Matrix Inequalities - LMIs) para sistemas lineares e invariantes ...
Projeto de controlador robusto LQR via desigualdades matriciais lineares
(Universidade Estadual Paulista (Unesp), 2022-01-24)
Neste trabalho, é apresentada uma nova abordagem com restrição de taxa de decaimento para a resolução do problema do regulador linear quadrático (do inglês, Linear Quadratic Regulator – LQR) baseada em desigualdades ...
Projeto de controladores LQR-LMI aplicados a sistemas dinâmicos
(2021-07)
Apresenta-se, neste trabalho, o estudo de projeto de controladores LQR via LMI para um helicóptero de bancada sujeito a falha em um de seus motores para as formulações em LQR clássica, estabilidade estendida via lema de ...
Stationkeeping controllers for Earth–Moon L1 and L2 libration points halo orbits
(2021-07-01)
This paper considers the dynamics of the circular restricted three-body problem (CRTBP) for the Earth–Moon system designing stationkeeping controllers at periodic orbits. Taking into account the L1 and L2 equilibrium points ...
Experimental identification and control of a cantilever beam using ERA/OKID with a LQR controller
(2014-01-01)
This paper presents an experimental study of the system identification and vibration control of a cantilever beam. For system identification, a white noise was applied, and the response signal was measured. These signals ...
Comments on ‘Less conservative conditions for robust LQR-state-derivative controller design: an LMI approach’ and new sufficient LMI conditions for invertibility of a convex combination of matrices
(2022-01-01)
This note is concerned with conditions on a set of non-singular matrices (Formula presented.), (Formula presented.), so that any convex combination of these matrices is also non-singular. The first part of the note points ...
LQR-LMI control applied to convex-bounded domains
(2018-01-01)
Recently, propositions of new conditions necessary and sufficient in the controller’s synthesis, based on linear quadratic problems, have been especially combined with the mathematical description in the form of Linear ...
