In this paper, the optimal criteria for the MTPA and MTPV current trajectories are analyzed based on the nonlinear flux-linkage model of IPMSMs. Firstly, the nonlinear flux-linkage model of the tested IPMSM is established by the experimental calibration method. The mathematical analytical ...
To validate the proposed torque control strategy, the whole system was simulated in Matlab/Simulink. The parameters of interior permanent magnet synchronous machine (IPMSM) are tabulated in Table 1. Table 1. Parameters of IPMSM. The rated speed was set to 1000 rpm. The machine speed was contr...
