Design of Frequency Control System Based on FPGA Technology

Based on steady-state model of induction-motor,SVPWM and FPGA was used as the core control elements to achieve variable frequency control.Based on the analysis of the relationship of voltage space vector and flux vector,and according to form a circular rotating magnetic field in motor space,obtained the formula of vector synthesis,and generated the output waveforms by writing operation module.Using FPGA to design can simplify the system hardware architecture,reduce cost and significantly improve the system′s processing capabilities.
