Development of a Software and Hardware Complex for Prototyping an Unregulated Asynchronous Electric Drive

The article is devoted to the development of a hardware and software complex for prototyping an unregulated asynchronous electric drive. The design technology is presented in three stages: development of a simulation model of the electric drive power circuit; development of an abstract automaton for electric drive control and generation of the machine's program code; creation of a software and hardware complex and emulation of the operation of an electric drive. The development of a simulation model of the electric drive power circuit was carried out in the Matlab-Simulink environment based on the operating algorithm of a typical circuit of an unregulated reversible asynchronous electric drive. An abstract automaton for controlling an electric drive is developed using the theory of automata, the mathematical model of which is presented in the form of a combined table of transitions and outputs and a transition graph, which is implemented in Stateflow. The machine code was generated for the CodeSys controller-programming environment. To test the resulting machine program, a visualization of the control and display panel was created. The software and hardware complex of the electric drive is developed using OPC technologies for inter-program data exchange between Matlab-Simulink and CodeSys. The article presents the results of emulating the operation of a prototype electric drive in all possible modes of its operation.
