Abstract
BACKGROUND: Sine-cosine rotary transformers, being electromechanical position sensors, have a relatively high accuracy and resistance to harsh operating conditions, which makes them attractive for use in automotive machinery and equipment installed on its base. Special controllers with software and hardware implementation are designed to generate excitation voltages, to process measuring signals and to calculate, depending on them, the angular position of the shaft where the sensor is installed.
AIM: Development of software and hardware for a controller of the position sensor based on a sine-cosine rotary transformer in the amplitude mode.
METHODS: Taking into account electromagnetic processes, which are the basis of the operation of a sine-cosine rotary transformer in the amplitude mode, system analysis methods, methods of software developing and debugging, methods of experimental researches and processing their results were applied.
RESULTS: A detailed description of the controller of a sine-cosine rotary transformer in the amplitude mode as well as its implementation using microprocessor technology and specialized tools for generating, capturing and processing signals are given. The structure of the controller software is given, as well as technical solutions aimed at improving the accuracy of measuring the angular position and the reasonable implementation of computational processes are described. The results of the experimental study illustrate the achievement of the given aim.
CONCLUSIONS: The development of a controller for a sine-cosine rotary transformer in the amplitude mode required the detailed consideration and coordination of electromagnetic, electrical and computational processes, as well as the use of various technical solutions aimed at improving the accuracy of measuring the angular position. The results obtained can be applied in the development of controllers for various electromechanical position sensors.
