A Rotating Speed Measurement Method of Rotary Table Based on SRF-PLL
摘要
Abstract
To solve the problem that traditional measurement methods of rotating speed of rotary table,such as method-M and method-T,cannot measure the real-time rotating speed,a rotating speed measurement method based on synchronous reference frame phase-locked loop(SRF-PLL)is studied.According to the characteristics of Moiré signal,the principle of rotating speed measurement method based on SRF-PLL is elaborated in detail.The FPGA-based rotating speed measurement circuit is designed,and the SRF-PLL design method in the circuit is explained.A rotary table experimental platform is established to evaluate the application effect of rotating speed measurement method based on SRF-PLL with the ring read of laser gyro as the reference value.The experimental results show that the rotating speed measurement method based on SRF-PLL has higher accuracy and stability compared with the traditional method-T and the consistency of effect of measurement can be maintained at various speeds.Therefore,the method of SRF-PLL can effectively improves the accuracy and stability of the rotating speed measurement.关键词
