Brief analysis of closed-loop control technology of vibroseis
As an important excitation source in seismic exploration,the vibroseis plays a very important role.However,the vibroseis itself includes multiple nonlinear subsystems such as mechanical,hydraulic,and ground systems,belonging to the category of multi input and multi output system nonlinear feedback,which is very dif-ficult to control.Classic open-loop control is not suitable for vibroseis,how to use precise linearization control to achieve robust global stability of a vibroseis control system is a crucial step.This article elaborates on the closed-loop system of a seismic vibrator,focusing on the architecture of the closed-loop system,multiple closed-loop systems,working principles,servo closed-loop control technology,and some factors that affect the closed-loop control system.
