Performance Evaluation of Microprocessor Control in Multi Motor Asynchronous Electric Drive Using Petri Nets

Öz

The paper describes the development of the electric diagram and description of the microprocessor control process for the multi-motor asynchronous electric drive with the use of bidirectional shift registers and resistor banks, the operation algorithm, the Petri net and the matrix method for the Petri net analysis. It offers to use contemporary mathematical apparatus the Petri nets in modeling, analyzing, synthesizing and describing logical operations taking place within a microprocessor control device of an electromechanical system, which allows increasing the level of automation in an industrial process, operational reliability, ensuring coordinated rotation of electric motors and better performance and cost efficiency.
