This project aims to implement a new method of command designated Method B, to optimize both the time response and frequency response, as well as to improve the profile of the intermediate frequency and the robust algorithm applied to a high-speed magnetic levitation system.
The basic idea of this method, patented by Professor David Bensoussan is based on considerations of the sensitivity of the compensated system. The magnetic levitation system is open-loop unstable. It is composed of a small metal ball immersed in the magnetic field of an electromagnet, the current is controlled by a digital processing unit in the input is read the sensor distance flotation of the ball.
Following a theoretical review of the countervailing B, the experimental set-up will be presented in detail, modelled and linearised around an operating point. Matlab simulations and Geogebra follow, and scanned algorithm will be implemented in Labview language in a digital processing unit. The contribution of this thesis is improved stabilization time average of a prefilter designed after time and frequency considerations. A number of consideration to minimize the control effect will be discussed.
The experimental results will be analysed and avenues for improvement will be advanced.
Finally annexes deal of varied theoretical, experimental setup presented in detail and simulation files Matlab, Labview and Geogebra.
This thesis was funded from the grant "Designing an experimental prototype making use of a new ultra-fast and robust control algorithm" of the program INNOV obtein by professors David Bensoussan and Benoit Boulet.
