To improve the dynamic performance of the deviation control system and solve the motor vibration problem,the deviation control algorithm is proposed,which is related to intelligent PD feedback control combined with the feed-forward regulation for the system deviation,and its MatLab simulation result shows.

To solve the strip deviation problem and the strip alignment performance is heavily influenced by the transport speed in winding process,this paper introduces an advanced deviation control system based on intelligent control which takes DC servomotor as actuator.

A new well straightening control method for improving vertical precision of vertical drilling trajectory;

From jacking construction,control survey,deviation rectification,stability calculation and other aspects the construction process of jacking pipe is introduced in order to ensure construction quality.

In light of the properties of incompact sand and silt,the paper introduced the scheme of thin wall caisson used in drilled pile foundation The posibitility of subsidence is predicted and the measures helping sinking are proposed in the sinking process The paper also analyzed the control of deviation rectification and correction of deflection during caisson sinkin

A brick-and-concrete building rectification study and application with lift-up method;

Strengthening and incline rectification of a building foundation;

Structure tilting reasons and analysis on sorts and characteristics of rectification measures

In this article,the author introduces a practical building inclination rectification and strengthening project in which engineers adopted the sinking\|well inclination rectification method to correct inclination of the building,and used anchor static pressure piles to strengthen rectification effects.

FEM is used to analyze the whole procedure of a raft foundation inclination rectification of a building.
