METHOD FOR REGULATING A THREE-PHASE MACHINE WITHOUT A MECHANICAL ROTARY TRANSDUCER |
摘要 |
A method is provided for regulating a three-phase machine functioning under any operational conditions without a mechanical rotary transducer. The machine is supplied with D.C. power by an inverter, where parameters of a D.C. link using an actual switching state of the inverter are detected for regulation. The method includes measuring (1) flow direction required for field-oriented control in asynchronous machines, and (2) rotor position for rotor-oriented control in synchronous machines. The measuring is performed by using spatial magnetic conductivity fluctuations in the machine. The conductivity fluctuations are detected using parameters for a D.C. link. An actual switching state of an inverter is used in the measuring process. Mathematical evaluation to calculate flow direction or rotor direction is then performed. |
