恒频恒压(CVCF)逆变电源的输出电压波形质量是衡量其性能的重要指标之一。文章采用一种重复控制和双闭环控制相结合的电压波形控制策略，以重复控制器提高逆变电源输出电压的稳态精度，减小总谐波畸变率；以双闭环控制器达到较快的动态响应速度。该方案在一台采用TMS320F240 DSP控制芯片的50 Hz三相PWM逆变器上得到验证。(Constant voltage constant frequency (CVCF) Inverter output voltage waveform quality is an important measure of its performance indicators. Paper using a repetitive control and the combination of double closed loop control voltage waveform control strategy to improve the repetitive controller output voltage inverter steady-state accuracy and reduce total harmonic distortion to achieve a faster dual-loop controller dynamic response speed. The program uses TMS320F240 DSP in a 50 Hz phase control chip PWM inverter has been to verify.)

In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization is an essential procedure for normal operation of the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.
