Method and apparatus for adaptive rotor-oriented control and torque estimation of a permanent magnet synchronous machine based on steady state magnetic flux estimates
Method and apparatus for adaptive rotor-oriented control and torque estimation of a permanent magnet synchronous machine based on steady state magnetic flux estimates
The invention relates to a method for operating a control device (1) for an electrical machine (80), wherein the control device (1) at different operating points of the electric machine (80) at least one actual current (i * 1, i * 2, i * 3, iα, iβ, id, iq) in the electric machine (80), wherein at least one magnetic flux (Ψd, Ψq) is automatically estimated during operation of the electric machine (80) and in at least one adaptive flow map ( 111, 112), wherein the adaptive flow map (111, 112) stores magnetic fluxes (Ψd, Ψq) associated with an operating point of the electric machine (80).
