- Abstract:
- A dynamical dq model is proposed for a linear flux-switching permanent magnet(LFSPM)machine which is suitable for high-precision control applications. The operation principle of the prototype machine is analyzed using the finite element method(FEM), and the parameters, such as the back electromotive force(EMF)and the phase flux linkage, are calculated. The calculated and measured results reveal that the back EMF and the flux linkage are essentially sinusoidal, and the variation of the phase flux linkage profile of the LFSPM machine is similar to that of the linear surface permanent magnet(LSPM)machine. Based on this, a dynamical dq model and a simulation control model are proposed. The simulation results are compared with the test results obtained from a DSP-based control platform, which verifies that the model is correct and effective. Moreover, the model can be used for design optimization and control development.
