@@@@To design the sinusoidal driving system for torque ripple suppression of hub motor based on the principle of Asymmetry Rule Sam?pling Algorithm. To generate two groups of three-phase Sinusoidal Pulse Width Modulation waves through the dedicated motor control chan?nels of MC9S08DZ60 and adjust both amplitude and cycle of sine wave in real time according to the information about both position and speed of the rotor provided by Hall position sensors so that the dynamic performance of the system can be ensured. The experimental results show that the system can effectively suppress electromagnetic torque ripple, having realized the smooth operation of the motor, met the low torque ripple requirement of hub motor of ultra-miniature electric car and verified both effectiveness and correctness of the design method given above.
