   Integrated reluctance position sensor for self commutation
By P-E. Cavarec; H. Ben Ahmed; B. Multon [View]
[Download]

Abstract: This paper presents a new design for a fully-integrated linear reluctance position sensor. Such a sensor is particularly well-adapted to compact hybrid synchronous linear actuators. A prototype has been developed and tested and a high-frequency simulation has confirmed the frequency behavior. Different types of demodulation are compared herein. A synchronous differential demodulation has been derived and yields very good results.

   Load Simulation based on an In-Parallel-Connected Converter Structure
By S. Trabelsi; W. Schumacher; A. Tolksdorf [View]
[Download]

Abstract: In the end of a production line a new built power converter has to undergo a series of stress tests. This can be achieved by connecting it to a dynamometer consisting of a three-phase machine joined by a rigid shaft to a DC load machine. The latter is controlled to create some specific load characteristic needed for the test. In this paper a test method is proposed, in which no mechanical equipment is needed. The suggested test stand consists only of a converter to be tested and a simulator converter. Both devices are connected back-to-back on the AC-side via smoothing reactors. The simulator operates in real-time as an equivalent load circuit, so that the device under test will only notice the behaviour of a three-phase machine under consideration of the load.

   speed observer in combination with an acceleration sensor
By J. Faßnacht; P. Mutschler [View]
[Download]

Abstract: In high precision machining and high dynamic control the availability of an accurate speed signal is of increasing importance. This paper presents the use of a state observer to improve the speed signal for servo drives with the help of a commercial acceleration sensor [1]. Methods to improve the acceleration signal with the help of the incremental encoder signal are also described. The measured results and the appropriate conclusions will show the possible performance, the advantages and disadvantages of such a system. The active damping of high frequent mechanical oscillations is shown in the paper which evidences the performance of the observer solution.
