| Abstract | Drives using AC motors produce a major impact both in many technical applications (transport, household appliances, industrial automation etc.) but also in various research studies. The advantages inherent in the operation of adjusting the frequency can not be fully exploited without adaptation of appropriate control strategies without determining the electrical machine parameters, stationary and dynamic regimes. This paper presents a snapshot of current trends of advanced control techniques with the possibility of determining the parameters (torque, power, speed, rotor position etc.). Are proposed for speed control without sensors analysis and estimation results based on very simple methods. It uses classical voltage and current transducers, showing how rapid technological progress in different fields finds a natural area of application in modern electrical applications. To analyze the operation of electric machines ordered through converters (inverter-corrector systems) must, mathematically, correction entry and exit inverter to be expressed in terms of alternatives sinus (a, b, c), as will be able to see this paper [1]. For an induction machine is preferable to use the stationary reference system (this system of reference is advantageous to use also for a variable reluctance machines or for the synchronous). It is also possible to represent mathematical equations corresponding electrical machine and its drive system in a rotational reference system. Ordered in an inverter for voltage harmonics from the machine terminals are produced mainly due process of switching the inverter, but can be influenced by the nature of load. Equations represented in a rotating reference system can be used to calculate the higher harmonics of the system using harmonic order reduction techniques. In this way you can create the necessary means for analyzing the dynamic behavior of systems that use all the corrector-inverter [2], [3], [4]. |
