| 摘 要： | 雷达测角用自整角机需要400 Hz正弦励磁信号。基于不对称规则采样法,采用高速DSP器件TMS320LF2407A实时计算生成SPWM参数。通过DSP丰富的片内资源,直接输出方向信号和半周SPWM脉冲,实现完整SPWM控制的目的,最终实现了雷达自整角机的励磁。实验表明,用DSP来实现SPWM励磁信号具有精度高、实时性好、结构简单等优点。 |

| Abstract: | To measure Radar angle with radar synchro motor demands excitation signal of 400Hz.On the base of asymmetric sampling,the research adopts high speed digital signal processor （DSP）TMS320LF2407A real-time calculation to generate SPWM parameters.The DSP which is rich in resources outputs direction signals and SPWM pulses,realizing complete SPWM controlling,and then achieves the excitation of radar synchro motor.This experiment indicates that excitation signals of SPWM with DSP has the advantages of high precision,full real-time,yet simple structure. |
