Abstract
In this paper an active power based Model Reference Adaptive Control (MRAC) is used for on-line rotor speed estimation of a vector controlled permanent magnet synchronous motor (PMSM). The advantage of this method is that the simplified expression of adaptive model does not contain any integral operation—hence the speed identification is somewhat robust and does not need any differential equation. The dead times and voltage drops of the power switches are compensated. Experimental as well as simulation results illustrate the practicability of the proposed method.
