The chaos research on anti-control of BLDCM of electrical vehicle

At present, the brushless DC motor control systems of electrical vehicle main drive are mostly vector control system or direct torque control, but during the actual running, the electrical vehicle will be suffered the impact of atmospheric chaos airflow, while commom control system ignores the impact. Chaotic brushless DC motor mathematical model is established in this paper, the delayed feedback and the tracking method are used on the main drive brushless DC of electrical vehicle for chaotic anti-control. Use Simulink system simulation, and gives Lyapunov values and simulation images. The content provides a theoretical basis for chaos anti-control of brushless DC motor of electrical vehicle main drive.
