The SVPWM Frequency Conversion Pressure Closed-loop Control System Based on DSP

On the basis of the space-voltage vector pulse width modulation(SVPWM) principle,one kind of the basic controlling algorithm was given based on DSP.And an asynchronous electric motor pressure closed-loop control system with the core TMS320LF2407A was designed.The methods of the software and hardware realization were introduced.The experiments show that this variable frequency variable voltage control strategy has been implemented with SVPWM.This pressure closed-loop control system is simple,but the function is reliable.All results indicate that the control system has excellent dynamic and static performances,which has broad prospects in application of the electric drive.
