Inductosyn Angle Measurement Method Based on the Pulse Subdivision

Abstract:

For the inductosyn angle measuring system axial angle digital converter integral loop and the VCO linear range restricted problem of tracking speed and control voltage, angle measurement system has been developed, the angle measurement system based on time subdivision method. The system mainly consists of rotary table, excitation power, signal pick-up circuit, FPGA control module, display module, and serial communications modules and host computer. FPGA is used as control core in the angle measuring system, and the high-speed FPGA signal processing has satisfied the measurement requirements. Induction signal is subdivided by high-frequency clock pulse. Angle measuring system has achieved angle measurement and communication functions. The experimental results show that the angle measurement system accuracy is ±3".
