Abstract:
    The invention is a DSP-based excitation controller data collecting and processing system and the operating method thereof, and it comprises on-off collecting circuit, AC analogue preprocessing circuit, frequency measuring circuit, A/D converter-DSP interface circuit, on-off output circuit, and phase shifted pulse forming and power output circuit. And its advantages: 1. simplifying hardware design; 2. using DSP chip with respect to motor and motion control field; 3. simplifying hardware overhead and reducing system maintaining workload by adopting AC sampling and omitting the electrical transducer from the excitation controller; 4. improving data collecting speed and accuracy and response real-time property of the excitation controller by data calculating and processing ability of DSP.
