Linear Parameter Varying Iterative Learning Control with application to a Linear Motor System

Alireza Karimi, Mark Edward John Butcher

In this paper an Iterative Learning Control (ILC) algorithm is proposed for a certain class of Linear Parameter Varying (LPV) systems whose dynamics change between iterations. Consistency of the algorithm in the presence of stochastic disturbances is shown ...

Modeling and Control of a Magnetically Levitated Planar Motor

Alireza Karimi, Roland Longchamp, Marc Kunze, Vincent Reymond

This paper deals with the modeling and control of a magnetically levitated planar motor. The actuator considered has moving coils and stationary magnets. The principal objective is to develop a model which can be implemented in simulation. Therefore, the d ...

Long-range energy transfer in proteins

Francesco Piazza

Proteins are large and complex molecular machines. In order to perform their function, most of them need energy, e. g. either in the form of a photon, as in the case of the visual pigment rhodopsin, or through the breaking of a chemical bond, as in the pre ...

Self-Sensing Methods from MEMs to Solar Aircraft Motors

Yves Perriard, Miroslav Markovic, Omar Scaglione

In order to control the speed and/or position of permanent magnet (PM) motors, they require position sensors. Basically, the auto-commutation needs 3 sensors for a 3-phase motor. In micro-motors, as there is no space for the sensors, self-sensing must be u ...

Self-sensing methods to drive micro-machines

Yves Perriard, Omar Scaglione, Jan Persson

Synchronous motors require sensors in order to control these devices in speed and/or position. Basically, the auto-commutation needs 3 sensors for a 3-phase type actuator. In micro-motors, as there is no more room to place the sensors, self-sensing approac ...

Comparative study and selection criteria of linear motors

Samuel Chevailler

Initially, linear motors have been particularly dedicated to transportation systems. Nowadays, linear motors are meant to replace a system using a rotating motor and a transmission to realize a linear movement. With linear motors the performances increase ...

Brushless DC motor optimization process - Choice between standard or straight tooth shape

Yves Perriard, Patrick Ragot, Miroslav Markovic

In order to create a new solar aircraft totally powered by the sun, a new method able to handle such a complex system must be developed. The project aim is to make a round-the-world flight in so as to promote the sustainable development. The aircraft power ...

Analysis of hysteresis losses in synchronous permanent magnet motors

Yves Perriard, Miroslav Markovic, Pierre-Daniel Pfister

The paper presents a method to determine hysteresis losses in synchronous permanent magnet (PM) motors. The method comprises four steps: (1) experimental determination of the B-H loop, (2) analytical modeling of the B-H loop by applying different models, ( ...

Simplified Design Methodology for a Slotless Brushless DC Motor

Yves Perriard, Miroslav Markovic

The paper presents a simplified analytical method to design a small two-pole slotless brushless dc motor. Using only a few approximations, the motor analytical model is formulated to generate a system of equations. The system can be solved analytically, pr ...

A contribution to energy saving in induction motors

Electric motors consume over half of the electrical energy produced by power stations, almost the three-quarters of the electrical consumption in industry and almost the half of commercial electrical consumption in developed countries. Motors are by far th ...
