   STRUCTURE AND CONTROL DRIVE OF FREQUENCY-CHANGER IN ENERGY CONVERSION
By G. Ledée; B. Seure; J. P. Hautier [View]
[Download]

Abstract: In the first part, the authors recall the running of a three to single-phase direct converter using full controlled switches. They purpose a parallel association so that to constitute a reversible power supply for two-phase asynchronous motor. Then, they give frequency changer architecture realized by coupling of a direct converter and an inverter which allows the reversible power supply for a three-phase load. In the last part, the microprocessing control drive architecture, used for the experimental realization is shown.

   PROCESSING OF COMMAND SIGNALS AND REDUCING OSCILLATIONS IN CONTINUOUS PATH ROBOT CONTROL
By P. Rojek; J. Olomskl; W. Leonhard [View]
[Download]

Abstract: General purpose industrial robots possess six or more degrees of freedom and a corresponding number of independent - usually electrical - drives with speed and position control. Continuous path motion, where the tool is to follow a reference path with small dynamic position error, calls for elaborate processing of command signals in combination with feed-forward control and active damping of undesirable oscillations. A multi-microprocessor system containing modern signal processors is capable of solving these demanding real-time control problems. Also the electronic power converter must be of sufficient control bandwidth in order to accommodate the command signals.

   ADAPTIVE STATE SPACE CONTROL FOR AXIAL WINDERS
By D. Schröder; W. Höger [View]
[Download]

Abstract: The stationary and dynamic behaviour of axial winders will be investigated. Axial winders are normally used in multimachine-drive-systems. The single drives of this system are coupled by an elastic web of paper, or other material, which should be processed. Starting from the results of the analysis of the stationary and dynamic characteristics new concepts with adaptive controllers on a state space approach will be developed. The results obtained from this new approach will be compared to the results of conventional approaches. Furthermore practical experiments show the advantages of the new concepts. Off-line identification of the system parameters can be realized with the computercontrol-system, so putting into operation is very much simplified.
