In the paper the principle of design and implementation of tools for developing and debugging the software of modern digital control systems of high-accuracy electric drives has been considered. Difficulty of learning and implementing the programming languages puts additional barrier for technical specialists, who are realising new ideas in field of control systems for complex electromechanical objects. Ready-to-use software complex MexBIOS provides significant reduction in time-to-market of electronic control units, achievement of required load characteristics and cost decrease of microprocessor control systems for electric drives. The software complex is an integrated environment of computer-aided design with ability to debug and adjust digital control systems for electric drives. Earliest versions of MexBIOS enable development of microprocessor control systems for electric drives in real-time mode, but programs, which have been developed by means of MexBIOS, were cumbersome. To provide visualisation and ease of understanding of the program flow a new concept of the designing the structure of the software complex have been elaborated. Now it is possible to implement complex algorithms. In late versions a new feature of state-flow programming has been added, i.e. of choosing separate states of the object and describing rigorously the control system actions in terms of these states. At present the program code can be modified without stopping the program run in order to modify the program structure of the control system without stop of the manufacturing process. The analytical relations and the synthesis procedure of vector control system for variable-frequency induction motor by visual programming method in new software environment MexBIOS have been developed.References
