This text puts forward of change the frequency adjusts to control the method a systematic design soon to realizes in brief and easily, adjusting soon the scope is big, the development responds to quick etc. characteristics.In system design process, TMS320C24X series DS conduct and actions system controller that this literary grace produce with the TI company of the United States.Not only satisfied single mutually the electric motor changes the frequency adjusts soon the solid hour that control requests, but eyes make the hardware electric circuit of the system become more in brief. Finally, would change the function parameter of the frequency empress to proceed the comparison with a function for adjusting soon hour electrical engineering parameter, contrast the result verified single mutually the electric motor electric voltage direction measures the type PWM changes the frequency adjusts soon possibility of controling the method.Changing the frequency adjust to is on adjusting more advancedly soon soon method. Key phrase:Changing the frequency adjusts soon single mutually the electrical engineering circulates the function
