Design Novel Fuzzy Logic Controller of IPMSM(interior permanent magnet synchronous motor) for Electric Vehicles
University of Science and Technology, Wuhan 43074, Hubei Province, China
The permanent magnets of the interior permanent magnet synchronous motor (IPMSM) are buried in the rotor core.
The advantages of the proposed FLC have been researched through experiment tests. The complete hardware drive system has been implemented by DSP TMS28335 for a prototype 50 kW motor. The test motor and the prototype EV are with same manufacturer.
As compared to the conventional FLC, the novel FLC has a faster speed response characteristic in the full operation region. The experiments show that the novel FLC can provide a better torque output capacity in the constant torque region, simultaneously, it can extend the operating speed limit in the constant power region. Moreover, the novel FLC reduced the copper lose because of the current adjuster. The superiority and the effectiveness of the proposed scheme have been proved by the experiments results.
