Methodology of Model-Oriented Programming Technique in Development of Electric Drive

Abstract

The materials presented in the paper are the result of summarizing the experience accumulated in the development of microprocessor control systems of the electric drive based on electric motors of various types using the model-oriented programming technique. It is shown that the specified technique and the tools of its implementation, in addition to automatic code generation, make it possible to detail the software to the level of individual subroutines, while maintaining the structure of the model developed at the modeling stage. In addition, it is shown that the tools of model-oriented programming technique allow the implementation of various technical solutions that improve the performance of the microprocessor control system. The development problems associated with the control of speed and position in the modes of speed stabilization and servo control, control in the technological system via digital interfaces, the formation of transient speed and trajectory processes and various auxiliary functions that improve the consumer properties of the electric drive are solved. The use of a direct current motor with independent excitation, a brushless direct current motor and a permanent magnet synchronous motor has been provided. The described development of the electric drive expands the practice of applying the technique and tools of model-oriented programming at the professional level. The experimental properties of the electric drive intended for use in various motion control systems are given.
