In this paper, the author has aimed at the variable-voltage controlled induction motor, analyzed the steady-state performance of variable-voltage thyristor controlled induction motor system, and presented the mathematic model and circuit model of such system. Power factor, as a significant variable to measure the efficiency of motor operation, is particularly studied in the paper, and the control strategy based on the studies of power factor and slip is given. The simulation curves and real waves are shown in the result. Finally, the transient performance of induction motor is mentioned. The analysis and results reveal that such system based on the special arithmetic is available.
In this paper a new approach to the problem of rigid body registration is proposed, using a concept of nonlinear correlation information entropy (NCIE) as the new matching criterion. The presented method applies NCIE ...

The lifting technique is now a well recognized tool for H∞ design and analysis of sampleddata systems. However, the efficiency of the method depends on the structure of the problem. The structure of the Ho sensitivity problem is analyzed in this paper. And the constraints on the H∞-optimization problem and on the design parameters in lifting design are also discussed. Under such constraints the resulting performance from the design is generally low. Therefore, the lifting technique can not be recommended as a synthesis tool for the sampled-data systems. An example is also given in the paper.
Input-to-state stability (ISS), integral-ISS (iISS) and their related notions of input/output stability and detectability have become a useful framework for nonlinear feedback analysis and design. in this paper, a new...
