2004 IEEE International Conference on Industrial Technology, 2004. IEEE ICIT '04. Pub Date : 2004-12-08 DOI: 10.1109/ICIT.2004.1490160

Wassermann","doi":"10.1109/ICIT.2004.1490160","DOIUrl":"https://doi.org/10.1109/ICIT.2004.1490160","url":null,"abstract":"Active magnetic bearings (AMBs) offer some advantages over conventional bearings such as contact-free suspension and variation of suspension parameters as stiffness and damping during operation. A lower reliability caused by a fairly complex assembly of the controller, sensors, actuators and amplifiers, however, is one major reason for the rather low industrial acceptance of AMBs. A study on failures in 200 magnetically suspended turbomachines clearly states that almost exclusively the switching amplifiers and their DC/DC-converters caused substantial electronic component failures. Based on the results of this study an AMB is being developed by the authors, providing a reliable and economic solution by means of spatial and galvanic isolation between the controller and the power elements along with a reliable switching amplifier (RSA). Depending on the reliability required, the RSA consists of two or more left and right switching amplifier half-bridges. These so called \"Hot Swap Modules\" (HSMs) are connected in parallel, each with its own error detection and decoupling circuitry (EDC). If an error occurs in an HSM, it is autonomously switched off and disconnects itself from the AMB-actuator, while the remaining, fully functioning HSMs take over the required current. The faulty HSM can be replaced by a functioning one during full operation of the AMB in a hot-swap procedure. In this paper the error detection and decoupling strategies along with explanatory measurement results of the first RSA-prototype are presented. All considered fault-scenarios (malfunctioning of switching elements, errors within the control signals, etc.) as well as the tasks of the EDC are explained. Measurement results show the reliable detection of induced component errors and the nevertheless almost undisturbed functionality of the RSA.","PeriodicalId":136064,"journal":{"name":"2004 IEEE International Conference on Industrial Technology, 2004.

The emulator can be used for research applications to drive an electrical generator in a similar way as a wind turbine, by reproducing the torque developed by a wind turbine for a given wind velocity. Also, it can be used as an educational tool to teach the behaviour, operation and control of a wind turbine. In this work, the turbine torque is reproduced by a DC drive. A control program reads wind velocities from an input file and calculates torque reference to the DC drive. A commercial DC drive with torque control is used to apply the commanded torque to the shaft of the electrical generator. Both, stall wind turbines and pitch controlled wind turbines can be emulated in the laboratory set-up. The emulator reproduced not only the mean torque of the turbine but also the oscillating torque due to wind shear and tower shadow. This functionality of the emulator can be used to investigate the effect of these phenomena in power quality. Experimental results are given which show that the emulator is an useful tool for the purposes already mentioned.","PeriodicalId":136064,"journal":{"name":"2004 IEEE International Conference on Industrial Technology, 2004.

The estimated speed is used as the feedback signal for the DFOC scheme to achieve the speed sensorless vector control.

A simple control algorithm is obtained by performing field orientation through state feedback. The latter, needs the measurement of the entire state vector, which is in practice impossible due to the presence of the unknown load torque. To overcome this problem, a linear observer is proposed to estimate this torque allowing the implementation of the state feedback control. To show the effectiveness of our control approach, simulation and DSP based experimental results are presented.","PeriodicalId":136064,"journal":{"name":"2004 IEEE International Conference on Industrial Technology, 2004.

They have adapted this method to their needs and realized a finger tracking in real time. In this paper, we propose the adoption of a simple and efficient tracking method applied to the magic-board. This method was inspired from the algorithm of Frederic Jurie & Michel Dhome. Knowing the position of the target in the first image, we can estimate the position of this target in the subsequent images by comparing the grey level values of the target pattern with the grey level values of the predicted regions (search region). The relation between the intensity variations and the position variations is calculated during the offline training stage. The proposed algorithm allows a better flexibility to the user of the magic-board. Our system can track the user's finger at any position in real time.","PeriodicalId":136064,"journal":{"name":"2004 IEEE International Conference on Industrial Technology, 2004.
