Abstract: The structure of a 12/8pole doubly salient electromagnetic machine(DSEM) was introduced in this paper。Through analyzing its basic working principle under motoroperation，a digital control system based on complex programmable logic device(CPLD) was designed and executed。By angel times frequency and exchange phase，this system achieved the standard angle control and advanced angle control in threephase threestate or threephase sixstate. Experimental results testify that the digital control system given in this paper can achieve the motoroperation experiment in every control strategy，and has some excellence such as high reliability ,fast dynamic response. At last，through the experiment waveform，this paper analyzed the relationship of DC voltage in different control strategy and the same output power simply.
