1. Analysis of magnetic force production in slider actuators combining analytical and finite element methods
The production of magnetic forces in a magnetic actuator is the focus of the present analysis. Magnetic circuit analysis is used to investigate the direction as well as the expected order of magnitude of the force that attracts the armature into the central portion of a stationary core. A sequence of finite-element based solutions is used to investigate magn

2. Local stabilization of linear systems under amplitude and rate saturating actuators
This note addresses the problem of local stabilization of linear systems subject to control amplitude and rate saturation. Considering the actuator represented by a first-order system subject to input and state saturation, a condition for the stabilization of an a priori given set of admissible initial states is formulated from certain saturation nonlinearit

3. Dynamic output feedback for discrete-time systems under amplitude and rate actuator constraints
This work proposes a technique for the design of stabilizing dynamic output feedback controllers for discrete-time linear systems with rate and amplitude saturating actuators. The nonlinear effects introduced by the saturations in the closed-loop system are taken into account by using a generalized sector condition, which leads to theoretical conditions for

4. Antiwindup design with guaranteed regions of stability : an LMI-based approach
This note addresses the design of antiwindup gains for obtaining larger regions of stability for linear systems with saturating inputs. Considering that a linear dynamic output feedback has been designed to stabilize the linear system (without saturation), a method is proposed for designing an antiwindup gain that maximizes an estimate of the basin of attrac

5. Global stabilizaton with improved performance for linear systems with actuator saturation
Este trabalho trata do problema da estabilização global de sistemas lineares com saturação nos atuadores. A estabilização global é obtida por meio de uma estratégia de escalonamento de ganho, aplicada a uma lei de controle parametrizada construída a partir de uma família de soluções da equação de Riccati (ARE). O algoritmo de escalonamento é g
