The article presents a novel control strategy for the control of Permanent Magnet Synchronous Motor (PMSM). The approach is motivated by the fact that PMSM are usually controlled by relays and thus only a finite set of control inputs is available. However in classical control design the use of Pulse-Width Modulation (PWM) ignores the relay nature of the… (More)

This article presents a parameter estimation algorithm for a magnetic bearing. Such process are inherently unstable systems with strongly nonlinear dynamics. Here, a simplified model of the magnetic bearing is developed. This enables to obtain a linear expression with respect to the unknown parameters. These parameters are measurable with difficulties, and… (More)

Abstract The standardization of a Return Channel via Satellite (DVB-RCS) and the satellite community efforts in term of interoperability over the last few years are expected to play, in a near future, a decisive role in Next Generation Networks (NGNs) through the integration of Satellite networks as an alternative to terrestrial networks like DSL (Digital… (More)

This paper is concerned with preliminary results on robot vibratory modes on-line estimation. The dominating oscillatory mode of the robot arm is isolated by comparing the robot position given by the motors encoders and an external measure at the tool-tip of the robot arm. In this article the external measurement is provided by a laser tracker. The… (More)

The article presents a novel relay control design strategy for some classes of nonlinear systems. The main idea of this work is to use an Linear Parameter-Varying (LPV) modeling to design nonlinear switching surfaces. This modeling is motivated by the fact that numerical tools such as LMI may be used by exploiting the quasi-linear structure of the system.… (More)

In many mechanical systems, only accelerations are available for feedback purposes. For example, certain aerospace, positioning systems and force-position controllers in robotic systems, use accelerometers as the only sensing device. This paper presents initial steps towards an algebraic approach for the state estimation based feedback control problem in… (More)
