Abstract: Abstract: The microseismic monitoring instrument is often used in downhole where the working conditions is complicated including sand, rock, mud and other impurities. In order to increasing the moving accuracy of the pushing device, an adaptive control method based on Fuzzy PID is proposed in this paper. This algorithm can optimize the output scaling factor Online, improve the control quality of the system. The simulation analysis and research of the traditional and Fuzzy system are carried out by using the Simulink platform under the Matlab software. The results show that the Fuzzy system is stable, fast response, small overshoot. The pushing device of microseismic monitoring instrument can be better satisfied the requirements for controlling.
