This paper develops an intelligent hybrid power system（IHPS）for extended-range electric cars. The IHPS solves the energy storage limitations of the battery pack and effectively increases the traveling distance of the electric car. This study established a hybrid power experimental platform that included a lithium battery module, an extended-range engine and a generator system, a permanent magnet synchronous brushless motor drive system, and an eddy current load system. Power output and efficiency tests of IHPS were run under various loads and speeds of the electric car motor. A permanent magnet synchronous brushless motor was designed with 5.5KW/DC310V/4100RPM. A motor vector control system was established using sinusoidal space vector pulse-width-modulation for inverter three-phase IGBT switching. Moreover, an interval type-2 neural fuzzy network （IT2NFN）with parameter adaptation laws was established for conducting online estimation of overall uncertainties from the variable loads and external disturbances. A robust controller based on IT2NFN was designed to ensure precise speed control for the electric car, which demonstrated favorable driving performance. Finally, simulations and experiments were performed using the designed hybrid experimental platform to demonstrate the effectiveness of the proposed control methodology.
