In this Paper we present in first place a new study method for AC Motor Dynamic Performances. This method is based on the Field Orientation Theory (Ref.1), applicated to the vectorial composition of induction motors magnitudes. Motor vectorial magnitudes are represented in field coordinates, flux-axis referred. Then we study the dynamic evolution of defined motor variables in rotatory vectorial diagrams. We include a new Induction motor state observer insensible to TR changes, that give us a satisfactory response to the accurate test for the real simulation of the AC motor functioning. The main state observers characteristic in any system to control and aplication is to reflect accurately their functioning either in steady state or transient state. To do this the state observers must know the internal changes that are going to happen in every system along its work. Finally, we present several simulations on AC motors, both regulated and non-regulated in order to show clearly the proposed study method. Simulations verify the accurate with real induction motor. |
