Measuring The Position of Current-Carrying Conductor Based On Mathematical Model Ajusted By The Method of Full-Scale Model Experiment

摘要

The article deals with the issues of measuring the position of plasma piston for controlling its travel and diagnosing magnetoplasma accelerator as complex engineering system. It is solved the inverse problem of determining a position of linearly moving conductor with currentfor any instant time on the known values of pick-off signals reacting to magnetic field of movable conductor. It has been suggested the mathematical model of the sensors allowing tosynthesize special functions of aggregate transformation of values for the purpose of obtaining a resultant function depended only on the dimension of moving conductor with current. For adjusting the model in the process of measuring it is used the method of full-scale model experiment. The conducted experimental research has shown that application of such approach enables to increase accuracy of measuringthe position of moving conductor with current in real time.
