May i know how to design the 3 phase converter for BLDC motor with Sinusoidal Commutation?

I have designed a BLDC motor model with Hall Sensors using simulink. It is working perfect with Trapezoidal commutation,with perfect trapezoidal back emf but when i go for sinusoidal commutation, the Hall sensors seem not to detect the electrical angle sequences. I want to know how to generate the three phase input voltages for driving the sinusoidally commutated bldc motor.Presently i am going with sensing the electrical angle using hall sensors and changing the hall state at every 60 degrees and switching the corresponding switches, but this somehow doesn't seem to work. I suppose i have to work on something like using a PWM signal or something. Please help me out.

when you go sinusoidal pwm its known as pmsm or pmac. it should be operated in 180 degree conduction mode.
