Description
  • Význam asynchronních motorů v řídicích aplikacích stále roste vzhledem k jejich jednoduché a spolehlivé konstrukci. Řízení pohonů založených na asynchronních motorech však představuje poměrně složitou úlohu. Pokud je použit algoritmus vektorového řízení,musí být známa nejen okamžitá rychlost rotoru ale i poloha magnetického toku. Ve většině aplikací není použit snímač magnetického pole a poloha fázoru magnetického toku je odhadována. Existují však i aplikace, ve kterých nechceme použít ani snímač otáče ek. V takovém případě je třeba řešit úlohu rekonstrukce neměřených veličin ze znalosti statorového napětí a proudu. V tomto článku je objasněna metoda deterministického vyhodnocení měřených veličin s použitím stavového rekonstruktoru, jehož odvození je založeno na Ljapunovově funkci. Metoda byla ověřena testováním na experimentální soustavě s asynchronním motorem. (cs)
  • AC induction motors become very popular for motion control applications due to their simple and reliable construction. 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. In most applications the flux sensors are omitted and the magnetic flux phasor position has to be calculated. But there are also applicationss in which even speed sensors should be omitted. 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 using the state observer based on Lyapunov function. The method has been proven in testing on real AC induction machine.
