Strategy for the Control of a Dual-stage Nano-positioning System with a Single Metrology

Denis Gillet, Philippe Müllhaupt, Yvan Michellod

A double-stage feedback control structure for a double-stage mechanical system, with a single optical metrology is developed to reach the nanometer accuracy at high bandwidth over large displacements. A piezoelectric stack actuator is used for fine positio ...

Enhancing the control of tokamaks via a continuous nonlinear control law

Jean-Yves Favez

The control of the current, position and shape of an elongated cross-section tokamak plasma is complicated by the instability of the plasma vertical position. In this case the control becomes a significant problem when saturation of the power supplies is c ...

Small Scanning Mirror Mechanism

Simon Nessim Henein

The CSE; has developed an optomechanical linear scanner. This scanner has a limited displacement range, performed with high resolution. The resolution is obtained through a very high precision motion guiding of the scanner itself. This paper describes the ...

JOE : A mobile, Inverted Pendulum

Alfred Rufer, Félix Grasser

The Industrial Electronics Laboratory at the Swiss Federal Institute of Technology, Lausanne, Switzerland, has built a prototype of a revolutionary two-wheeled vehicle. Due to its configuration with two coaxial wheels, each of which is coupled to a dc moto ...

Implementation of a lowcost sinusoidal supply for BLDC motor

Yves Perriard, Frédéric Bonvin

In many applications, industry has tried to develop sinusoidal supply for brushless DC (BLDC) motors. This paper describes a method that still keeps a simple 2 phases-on sensorless method and achieves sinusoidal supply, which is needed to avoid speed oscil ...

Sensor-less control of linear induction motor considering its asymmetric parameters

Alfred Rufer

When we achiev a good performance of the field-oriented vector control system, it is necessary to detect the speed and flux of the motor. Usually it is hard to implemment these sensors. Then the sensor-less contro-system techniques using the observer inste ...

BLDC motor control in multiple dq axes

Yves Perriard, Frédéric Bonvin

With brushless DC Motor (BLDC), current regulators in dq axes are very appreciated for sinusoidal supply. As the set current is constant, the regulator works properly. When the back-EMF is not sinusoidal, current oscillations appear in the dq regulator. A ...

Vector Control of an Induction Machine in a Stator Flux Reference Frame.

Jean-Jacques Simond, Basile Kawkabani, Mai Tu Xuan, Alexander Schwery

This paper describes a stator flux oriented control strategy using state space controllers. The optimal determination of the different controllers parameters leads to an independent control of the stator flux and the torque. The effects of undesired offset ...

Synthèse multimodèle d'un régulateur polynomial robuste

Yves Henri Philippe Piguet

Two new approaches are proposed for the multimodel synthesis of a two-degrees-of-freedom polynomial controller : the multimodel pole placement and the multiobjective optimisation. Using several models enables taking into account the parametric variations o ...
