State Observer for Sensorless AC Induction Motor Control

Popis výsledku v původním jazyce

Control of drives based on AC induction motors is a quite complex task. Provided the vector control algorithm is used we need to know not only the rotor speed but also the position of the magnetic flux inside the motor during the control process. There is of course the possibility of using flux and speed sensors and a control based on measured values. Flux sensors are quite complicated and expensive, that is why it is good idea to use computed values of the flux instead of measured values. But there aree also applications in which even speed sensors should be omitted to achieve cost reduction and simpler mechanical construction. In such a situation, we have to solve the task of state reconstruction only from voltage and currents measurements. In the current paper, we present a method based on deterministic evaluation of measurement. The method uses a set of equations based on the AC induction motor model to estimate rotor flux and speed from measured electrical quantities. The main adv
