  4. In the system, control unit accomplishes back - emf zero - crossing information reading and closed loop commutation. the system eliminates the pwm interferences and the commutating interferences by filtering with software algorithm. in order to make the bldc commutate exactly, the method of three - point estimation is used for phase locking in the system. the system also accomplishes several important objects, such as tmppt of photovoltaic arrays, unmanned supervision of the system, fault detection etc. the results of the experiment show that the device, which is made on the base of the principle above, can control the motor to complete the exact commutation
