| Abstract: | The principle of the digital electrostatic feedback system developed with computer technology and control algorithm of digital PID(Proportion Integral Derivative) control is systematically introduced.In addition,it is the first time in China that this new system is successfully used in the update of LaCoste & Romberg(LCR) ET20 gravimeter.The experimental results of the LCR ET20 gravimeter with the new system installed show that problems of analog electro-feedback system,such as the difficulty to adjust line... |
