Abstract

A speed observer for field-oriented controlled induction drives is presented. The proposed solution exploits the concept of the classic full-order flux observer which is adaptive to the rotor resistance variations. Due to the structural similarity of the rotor speed and active rotor resistance in motor model, the speed observer can be designed using similar structure. The observer guarantees local asymptotic estimation of the rotor fluxes, stator currents and rotor speed in all operating conditions, excluding DC stator excitation. The stability properties of the observer are studied using Lyapunov’s second method. It is experimentally shown that the observer provides an acceptable dynamics of the speed estimation if speed is slowly varying. The proposed observer is suitable for the applications with medium requirements for speed regulation performance. References 13, figures 5.

Abstract

У статті йдеться про застосування екстремального енергоефективного керування для двох послідовно з’єднаних насосів. Один з насосів укомплектований частотно-керованим асинхронним електроприводом. Представлено опис алгоритму екстремального керування та структурна схема системи. Наведено порівняння ефективності екстремального керування з системою стабілізації тиску. The paper concerns the application of the extremal energy efficient control for two pumps connected in series. One of the pumps is with the controlled induction motor drive. The extremal control algorithm description and the system block diagram are presented. The efficiency of the control compared with the head stabilization system is shown.

26. Interactive energy saving automatic control of water supply pump

Author

Kiselychnyk, Oleh, Koláčný, Josef, Buryan, Serhii, and Ondrák, Tomáš

Subjects
interactive control, technical realization, pump, Mathematical formalization
Abstract

Link to publisher http://www.elektrorevue.cz/cz/o-nas/ The article is devoted to a novel approach to energy saving in water supply systems. The idea of interactive control of the pump bases on consumers behavior during water consumption and is realized as some game of the system and consumers. Fundamentals, simulation and technical realization of the controller are presented.
