基于FPGA的变频控制系统的实现
Design of frequency control system based on FPGA
摘要
Abstract
To solve the problems of timing disorder and phase jitter existing in the space vector pulse width modulation(SVPWM) realized by digital signal processor (DSP), a new idea is put forward for the frequency control system based on field programmable gate array ( FPGA). Combining the SVPWM, direct digital synthesizer (DDS) is used to generate sinusoidal voltage modulation instead of DSP and the traditional SVPWM algorithm is optimized. Furthermore, the switching vector time is allocated and reconstructed when the five-style principle is utilized to synthesize space voltage vector , which reduces the occupancy rate of logic units for FPGA. Finally, the algorithm is simulated in Quartus II and verified by experiments. The experimental results show that the proposed SVPWM algorithm is real-time and reliable, and it can be used to achieve precise frequency control, which meets the requirements of the variable frequency control system.关键词
