Human leukocyte antigen (HLA) genes are very informative in population genetics studies and their variability has been widely used to reconstruct the history of geographic and/or demographic expansions of human populations. The characterization of HLA diversity at the population level is also fundamental in clinical studies, particularly for bone marrow transplantation programs. In this study, we...
This work addresses the problem of local stabilization of rational systems considering magnitude control constraints. Based on a Recursive Algebraic Representation (RAR) of the system and on a generalized sector condition, stabilizing conditions in the form of linear matrix inequalities (LMIs) are proposed to compute a saturating state feedback control law that ensures the local asymptotic stability...
This paper focuses on the problem of designing stabilizing state feedback control laws for rational nonlinear systems subject to actuator saturation. The results are based on the differential-algebraic representation of rational systems and a generalized sector relation to address the saturation effects. From these elements, LMI based conditions are devised to compute a state feedback control law...
This paper focuses on the problem of static anti-windup design for a class of multivariable nonlinear systems subject to actuator saturation. More precisely, a convex approach is proposed to compute a static anti-windup gain which ensures regional stability for the closed-loop system assuming that a nonlinear dynamic output feedback controller is previously designed to stabilize the nonlinear system...
This paper addresses the stability characterization problem for a class of nonlinear discrete-time control systems subject to actuator saturation and energy bounded disturbance inputs. The considered class of systems covers all nonlinear discrete-time systems that can be modeled by rational difference equations. The results are based on a recursive algebraic representation of the nonlinear control...
