Solomakha O. Improvement of control systems of asynchronous electric drive in irrigation systems

Object is static and dynamic processes in asynchronous electric drive with vector control of irrigation systems. Purpose is energy saving in asynchronous electric pumps of irrigation systems using vector control of induction motor, and LC-filter at the output of the frequency converter and injection for identification the active resistance of rotor are applied. Following methods of research are used: the modern theory of automatic control for continuous and discrete systems and adaptive control with parameters identification, theories of electric drives methods and space state methods, methods of numerical and physical modeling. The practical significance of the results is improvement of vector control using LC-filter and injection. Scientific novelty of the results is developed scientific bases of system design with precompensation and improvement asynchronous electric drive model with vector control. The developed control system is implemented in industrial and in educational process. The research results are the scientific basis for their practical application in modern irrigation systems, in particular for the implementation of agricultural enterprises, which are located in the southern Ukraine.
