Nevertheless, in some specialized fields, it is not convenient to use position sensor. This paper presented a control system of sensorless brushless DC motor ( BLDCM ) based on DSP.The electric bicycle brushless DC motor as the research object, the digital signal processing chip TMS320F240 as the processor American Texas Company,while the use of the Kalman filter algorithm, enabling the software and hardware design and control strategy of the system.In addition, it also uses the voltage zero crossing detection method to extractthe signal of rotor position, eliminates the depth filter with superior performance of DSP, the use of pre-positioned starting method and analyzed in detail.Bui
